I want to include a small modification into voucher code.
Currently it works great, but I want to add a new feature.
In my case, a merchant is giving a voucher code for all products, except some of them. So I want a new "Match Criteria" that excludes the products specified.
If I set:
#merchant => Merchant
#match_type => Exact Match (NOT) (*)
#match_field => name
#match_value => product 1, product 2, product 3
All the products from that merchant would be discounted except for product 1, product 2, product 3
(*) This would be new
