You give a customer a 10% coupon after their first order.
They use it.
So you send another 10% coupon after the second order. They use that one too.
After a while, you have to ask an uncomfortable question: are you actually building retention, or just teaching customers to wait for a discount?
For a PrestaShop store, a coupon can be more than a one-off promotion. It can also be part of a repeat-purchase strategy. But the effect depends on the customer, the timing, whether the coupon actually gets used, and what happened before it was issued.
Give the coupon a reason to exist
Compare these two offers:
10% off your next order
and
Thanks for your first order. Here’s 10% off your next one.
The discount is identical. The second one has context.
This gets more interesting when coupons are tied to actual events: a customer registers and gets a welcome coupon, places a first order and gets a coupon for the next one, orders again and gets another reward. In PrestaShop, a store can generate a unique coupon automatically at each of those moments, with its own value, expiration date, and restrictions.
The useful part is the connection between the coupon and the event that triggered it.
Sent isn’t the same as used
There’s another catch: receiving a coupon and redeeming it are two different things.
A 2023 study of electronic coupon promotions at a large online platform found a clear difference between the two groups. Customers who received and redeemed coupons made more purchases after the promotion than customers who didn’t receive them. Customers who received a coupon but didn’t redeem it actually purchased less than the control group afterwards.
That makes “20,000 coupons sent” a pretty weak retention metric.
More useful numbers are redemption rate, repeat purchases, revenue from those customers, and the margin left after the discount.
And one more question is worth asking: would the customer have bought anyway?
A repeat purchase after a coupon doesn’t automatically mean the coupon caused it. Sometimes a store is simply discounting someone who was coming back regardless.
Timing can matter as much as the discount
There is also a less obvious problem: when should the next-order coupon become active?
This isn’t a hypothetical case for me — it’s a support ticket I remember. A PrestaShop store owner using Advanced Coupons had a customer place a large order, get a reward coupon for their next purchase almost immediately, and then return that order. The reward was already available even though the order that triggered it was later returned.
We added an option to delay activation of a repeat-order coupon until the return window closes specifically to handle this kind of situation. The reward can then become active only after the original order has had time to become a completed transaction.
So, can a coupon bring a customer back?
It can. But a useful retention coupon usually has a reason behind it: something the customer did, a sensible time to use it, and conditions that make sense for the store.
That’s very different from simply putting “10% off your next order” in an email and hoping the customer comes back.
