I have 2 coupon number in my coupon list but I can’t use them. I can not register those on my registration code section and also when I tried to check out and I input my coupon number, it says “invalid coupon number”. My total amount was around $500 and regular priced item was definitely over $100. I don’t know why I can not use 5% off app download coupon either new customer coupon. Please don’t tell us it will automatically apply. Please try yourself and answer this question. I try to help you out not to loose your future customers.
