Can anyone know how to put a "Redeeming coupon code" box to my shopping cart page? Please help!

This is not an easy task. There are a lot of code and logic needed to make this work.

As far as I know the only available option is through paid module.

Hello!

I've created the coupon code on my admin, now I just want to know that how can my coustomer to "redeeming coupon code" during checkout? Is there some code I need to put on my .php files?

Attached picture is what I saw on the other website which is what i want!

Please help! Thanks!

Zen Cart allow customer to redeem their coupons in the checkout process. It doesn't allow the store owner to choose what page to display that on. It is not just a simple code that you can copy and paste to get it to work on the shopping cart page.

The module is available as a paid module. You can google it. I don't think we are allowed to provide this information in the open forum.
