Powerstore User Discounts
I've added a column to the ps4_users table called UserDiscount that is populated when an admin updates a users details in the admin side.
A data example might be 0.15 for a 15% discount.
I need to know what files I need to modify to correctly add this discount and the code to add.
It looks like the WA_Store_Cart_PHP.php file is a good place to start but want an WA expert opinion first.
