How to get this script
This script is a commercial script available fully installed by me at a cost of $100,
though the first 3 get it for $50. It is the ONLY coupon script that has been re-written for 2.3.1 and is the ONLY coupon script that (as far as I am aware) allows the coupon to be applied at the Shopping Cart Stage. If you would like this professionally installed with minimum of fuss, email me on oscshops AT gmail DOT com
