Hello, I'm looking for a script to make coupons online. Lube station, pizza shop, car wash etc would create an account and generate their own coupons online then pay for them online with credit card / paypal. After 30/60/90 days they would expire and they can go back in and buy another coupon. The coupons would be displayed in different categories. The script needs to run on Linux Does anyone know of any good ones. Thanks
