CUM Books: How SA’s Largest Christian Bookstore Wins Online

CUM Books is South Africa's largest Christian bookstore chain, founded in 1939 by Freddie and Ria Crous and now running 34 stores plus a national online store, per CUM Books' own about page. Online, it wins by doing the boring stuff with discipline: Google Performance Max for acquisition, email and Meta for retention, and a Shopify store with payments that actually convert. We pulled the playbook from our interview with Michael Pretorius, CUM Books' e-commerce manager. Below is what they do, and what you can steal for your own store. From V8 Media, the team behind R2+ billion in client sales.

What is CUM Books, and why does its online story matter?

CUM stands for Christelike Uitgewersmaatskappy. In English, the Christian Publishing Company.

It was started in 1939 by a couple, Freddie and Ria Crous, who felt called to spread faith through the printed word, per their about page.

That is 80+ years. Most retail brands barely last 10. The chain you see today grew out of a real calling, not a spreadsheet.

This is not a "slap a logo on it" brand. The reason the business exists is real, and customers feel that.

Today CUM Books has 34 stores across South Africa, plus an online store that ships nationally.

That mix matters. Physical shops build trust fast. Online makes that trust scale. Both, not either.

But here is the cold truth Michael said out loud. Trust helps, but trust does not complete payments.

A customer can love your brand and still bail when the checkout spins like an old Eskom turbine. Friction kills sales quietly.

Here are the fast facts before we get into the playbook.

So why does a bookstore matter to your business? Because the logic works for any store.

You do not need 34 branches to win online. You need clarity on what you sell, who you sell it to, and why they should trust the transaction.

Scale is optional. Fundamentals are not.

How does CUM Books compete online without "reinventing the wheel"?

Michael's view is refreshingly unromantic. They do the basics well, then repeat what works.

The basics are simple. Acquire customers through the right channels. Price correctly. Give great service.

Sounds obvious. That is exactly why most owners skip it and chase shiny tactics instead.

His best line was "simple, but not easy." Getting the foundations right takes discipline and the guts to be boring on purpose.

Because nothing screams "amateur" like random tactics with no tracking. Consistency beats chaos, even when chaos is wearing a trendy hoodie.

Pricing is not a feelings exercise when you sell online. If your product is meaningfully pricier than the next store, you can bid perfectly and still lose.

The algorithm will not rescue a bad offer. Good ads cannot fix a bad deal. Full stop.

And remember who you are really up against. Not the bookstore down the road. Takealot and Amazon live rent-free in every shopper's head.

Your real competition is the customer's impatience. And impatience has the attention span of a goldfish on payday.

Here is a checklist you can run this week.

• Your product pages must answer questions before they get asked.
• Your pricing must be competitive where it matters most.
• Your checkout must be fast, stable, and familiar.
• Your customer service must solve problems, not create new ones.

Why is Google Performance Max CUM Books' number one channel?

We asked Michael a brutal question. If the CEO let you keep only one channel, which one?

His answer was instant. Google. Specifically Performance Max, because that is where most of their new customers come from right now.

No hesitation. No hedging.

The reason is simple. Google captures demand that already exists. People search with intent, not curiosity.

They started by testing Google Shopping. When the ecosystem moved to Performance Max, they tested that too.

The early results were strong, so they shifted real budget into it. That is how good strategy works. Test, see results, move the money, repeat.

Their full mix is Google, Meta, email, and organic search. The paid split between Google and Meta sits around 60/40 or 70/30 depending on the month.

Seasonality moves that split, especially around Mother's Day and Father's Day. The budget follows demand, not ego.

This is the same engine we run for clients on Google Ads and Meta Ads. Win the click where the intent is, then close the sale.

On metrics, Michael warned about drowning in analytics. They keep it practical. Return on ad spend, cost per click, impressions, and clicks.

You can track 50 micro-metrics and still miss the point. Revenue with margin is the scoreboard.

Here is a performance checklist that keeps you sane.

• Track ROAS, but read it next to margin so you do not celebrate loss-making "growth."
• Track conversion rate by device, because mobile problems hide in plain sight.
• Track your product feed health, because feed issues look exactly like "ad problems."
• Track your top categories on their own, because the 80/20 rule changes your priorities.

If margin is a foreign word in your ad reports, start with our guide on ROAS vs POAS for ecommerce. POAS means profit on ad spend, and it is the number that pays your bills.

Why PMAX and pricing are secretly best friends

You cannot bid your way out of being overpriced.

If your price is higher than the competitor, you will not reliably win the top spot, no matter how clever the campaign.

That is why pricing and ad performance are joined at the hip. Winning the click is easier when the offer is sharp.

So before you blame the ads, check the price tag. The market is comparing you in real time.

How do email and Meta keep CUM Books' revenue stable?

Meta is mostly a promotions channel for them, with past wins in lead-generation contests and giveaways.

The idea is simple. Build the database. Then market to it again and again.

Email is not "old school." It is owned distribution. You do not pay Zuckerberg a toll every time you send it.

Their email rhythm is twice a week, with extra sends around big promotions like Black Friday.

The smart part is not the frequency. It is sending to engaged subscribers. A small engaged list beats a big ignored one.

They also mix content with promotions. Constant discounts train customers to wait for the next sale.

Highlighting new releases and featured titles gives value even when there is no deal on. Content earns you the right to land in the inbox.

Automations are the heavy lifters, and they run the essentials through Klaviyo. Michael said the welcome flow drives the most revenue, helped by a first-time signup discount.

That tracks with the wider data. Klaviyo's ecommerce email benchmarks rank the welcome series among the highest-earning automated flows, around $3.34 per recipient for stores with average orders of $100 to $200.

That makes sense. Warm intent converts faster than cold persuasion.

Here is the automation baseline you can copy this month.

Automation	Job it does
Welcome series	Delivers value plus a first-order reason to act (their top revenue flow)
Abandoned cart	Removes friction and answers objections before the customer cools off
Post-purchase	Asks for reviews and nudges the next purchase
Transactional EFT reminder	Recovers missed manual payments without a human chasing them

The conversion stack: Shopify, pricing intelligence, and payments that do not fail

CUM Books moved from Magento to Shopify. Michael called it a turning point.

The reason is practical. Shopify is easier to run in-house without leaning on heavy development.

If you can ship improvements weekly, you beat the team that only "plans" improvements every quarter.

They use a pricing intelligence tool called Price2Spy to watch competitor prices. Then a human decides whether to match, based on margin and strategy.

This links straight back to PMAX. Price affects ad competitiveness, so the two work together.

Then came the payment wins, and this is where real money moved. They added Stitch Payments alongside PayFast.

They shifted card transactions to Stitch and kept PayFast for other options. Conversion lifted, even with a few changes happening at once.

Payments are not admin. They are conversion infrastructure. Treat them that way. Read how the rails work in how Stitch is changing the payments game.

They also saw strong adoption of digital wallets. Apple Pay and Capitec Pay became a meaningful chunk of sales.

Those options cut friction and cut typing. Punching in card details on a tiny phone screen is a hobby nobody asked for.

Most "it did not work" experiments actually failed because nobody fixed the friction first. We dig into that in why your online store conversion rate is dropping.

Here is a conversion upgrade plan you can run this month.

1. Audit your checkout on mobile like a normal, slightly annoyed customer.
2. Add payment methods people already trust, like instant EFT and wallets.
3. Show shipping costs early, and offer a pickup option where you can.
4. Install a free tool like Microsoft Clarity and watch where users get stuck.
5. Improve search if customers use search more than your menus.

Behaviour is feedback, and feedback is free. Stop guessing and go watch the recordings.

Shipping strategy: why the free-shipping threshold is set, not guessed

CUM Books offers free shipping above R500, and that number is not random.

The threshold is shaped by two things. What their margins can carry, and what the big competitors have trained customers to expect.

You cannot set a threshold in a vacuum. Shoppers compare across stores in seconds.

Shipping is not logistics. It is marketing. Treat it like a leak, not a line item.

They added more delivery options, including Pargo as a lower-cost pickup point.

Pargo helps people who cannot receive parcels at home during work hours. It also serves rural customers who may not have a formal street address.

Convenience is a real edge when money is tight. And in South Africa, money is often tight.

In-store pickup is on their roadmap, and it fits a business with 34 shops perfectly.

Pickup cuts courier costs and gives the customer control. It also drives foot traffic, which usually lifts basket size.

Sometimes the best online move is using your offline advantage.

Delivery option	Who it wins
Courier to door	Convenience buyers who want it at home
Pargo pickup point	Cost-conscious and rural buyers
In-store pickup	Speed, trust, and extra in-store spend
Clear delivery timelines	Everyone, because surprises kill carts

Black Friday: why CUM Books runs one week, not a whole month

Their Black Friday plan has stayed the same for years. One week, 20% off storewide on items not already discounted.

The reason is urgency. A week creates pressure. A month creates procrastination. Simple as that.

Loads of brands now stretch it into "Black November." That quietly changes buyer behaviour.

Customers start spending earlier, so by the big day their wallets are already lighter. You end up fighting everyone for the first bite of payday.

First to the wallet often wins, even with an average offer. This is the same payday logic we cover in why neglecting urgency and scarcity costs you sales.

During the week they raise budgets and adjust automations. They shorten abandoned cart timing because inbox competition is brutal.

Speed matters when customers are shopping ten sites at once. Timing is a conversion lever, not a nice-to-have.

They also see stronger sales on expensive products that are rarely discounted. A rare discount on a big-ticket item gives customers permission to act.

That is why your everyday pricing matters. Black Friday should feel like an event, not a rerun of last week.

AI, search, and the future: what changes, and what stays human

Michael flipped the interview and asked us how AI will change ecommerce and marketing.

Honest answer? Nobody knows. But you do not need certainty to act. You need a direction and a way to measure it. Strategy is just making a bet with the info you have, then checking if it paid off.

AI changed SEO because content got faster and cheaper to make. When everyone produces more at the same speed, "more content" stops being a strategy.

The new edge is usefulness, originality, and proof. Real numbers, real experience, real opinions.

Search is shifting too. People increasingly ask AI tools for recommendations instead of scrolling ten blue links.

That creates a new question for brands. How do you become the option the AI recommends?

A practical move is to ask the AI what it recommends, ask why, then improve what you control. This is exactly the AIEO thinking we apply to client content.

Here is what AI cannot replace. Trust. People still trust what feels human, and that is not going to change.

AI can spit out a perfect-looking ad. But perfect-looking is not the same as believable. Customers know the difference now. Be the brand that sounds like a person, not a press release.

The CUM Books playbook you can steal without asking

You do not need 34 stores or an 80-year head start. You need the discipline.

Here are the moves baked into how they run online.

1. Do the basics relentlessly. Right channels, right pricing, great service. Simple, but not easy.
2. Lead with the channel that captures intent. For them that is Google Performance Max.
3. Treat email as owned revenue. Engaged list, welcome flow first, content mixed with promos.
4. Fix payments before you blame the ads. More trusted methods, fewer drop-offs.
5. Set shipping thresholds on margin and market, not vibes. Add pickup options for SA reality.
6. Make Black Friday an event. One sharp week beats a tired month.

That is the whole game. Fewer leaks, not louder ads.

How V8 Media grows ecommerce brands

Most agencies just send more traffic and call it a win. If the store does not convert, traffic only burns money faster.

We bring the right buyer in with Google Ads and Meta Ads. Then we make sure the store actually closes them.

That second half is where most agencies quit, then wonder why the ROAS never reaches the bank account.

We have done both since 2018. R2+ billion in client sales. See how we grow ecommerce brands profitably.
