up to 3 Products from one Category get Coupon

Hi HikaShop,

First of all...wonderfull work. This is the one and only Shop Component for Joomla.

I have a problem and can´t find a solution for that in the forum.

I am searching for a way to get
automatic coupon when a client put 3 or more products from 1 category in the cart.
I have allready tried some things like playing around in the scripts and database but cant find a way to handle this.

What be awsome to get some help and hope i haven´t double post this topic.

Best Regards
Chriss

Sorry, i´ve found the solution after 3 days:)

it seems to me that the coupon code is just working correctly with one category and not subcategorys.
so i think now its working perfectly....
