I'm sure somebody already done that with AgoraCart, but as the forum's Search tool is off i tried to have a look but didn't find a post about this...
How would you integrate a field in the cart display to allow clients to enter a voucher number so they can have a discount ?
It would happen when they finished shopping, just before they confirm order and access to the payment page.
Thank you for your help

PS - By the way, if i install Agora 5, will it do changes on my options and settings, and will it make any change for clients, or will it just change my store manager possibilities ?
