A customer enters a discount code at checkout, but PrestaShop refuses to apply it.
The coupon exists, it’s active, and it may even work perfectly in your own test account.
Before looking for a checkout bug, open the Cart Rule and check its conditions. PrestaShop validates more than the coupon code itself, and a small restriction can be enough to reject it.
A birthday coupon sounds simple: give the customer a discount and send a nice email.
But someone needs to check birthdays every day, generate the coupons, and make sure the emails go out on time. And what if the customer already has another discount? Or has never placed an order?
Want to give new customers a discount when they sign up for your PrestaShop store?
For example, you could offer €5 off their next purchase or a 10% welcome discount.
PrestaShop lets you create discount codes with Cart Rules, but it doesn’t automatically generate and email a personal coupon when someone registers.
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?
