I need to add coupon codes for a e-com shop built using Drupal Commerce, and have been playing with Commerce Coupon and Commerce Discount modules, but I can't seem to fix the problem of coupons being removed during checkout. This has been reported many times (see issues below), with various supposed fixes but I've tried everything and nothing works.
So, is there any alternative for this kind of functionality?
I really only need discounts on full orders (instead of products) but do need both percentage and fixed price options.
Alternatively if anyone has a real fix for the issue please let me know!
