I like you your Loyalty Program idea, it working well now, I am facing another challenge with it, customer now can accumulate point thru buying product and also gift certificate, the Balance they can use to pay their future spend, if customer have discount coupon in hand, how to make deduct a discount first before charge with gift cert Balance. for current I tried both discount coupon and pay with "balance" active, it will zero the full payment (with enough Balance) no discount was given, I tried configure choose activate "multi coupon" and "render gift certificate last" doesn't help.
please advice.
