[Contribution] Discount Coupon Codes in General Add-Ons Support Posted October 16, 2011 · Edited October 19, 2011 by Jan Zonjee I have a question. I'm using discount coupon for 2 year now, but I still have a problem. I guess normally SELECT FROM discount_coupons ORDER BY discount_coupons.coupons_number_available coupons_number_available must decrease each time we use a coupon? No Because if no way to clear my coupon list, an delete the one use? Does normally coupons_number_available decrease, where this is done?
