ovidiu.buksa: 05.03.2013: When inserting a new coupon in the db and be able to use it in storefront, the record of the coupon MUST have a product id. It has been observed that the product id is the same for all the coupons: the serialisation of the array containing the key-word "include". The version of CubeCart in which this was introduced is 5.1.5, but kept compatibility with older versions of CubeCart in which this worked with the product id ''.
