Their coupon system is either a scam or programmed by developers who should find another career. I was trying to buy something for Mother's day and my wife pointed out shoes she wanted and a coupon code she'd like to use (I hate coupons, but they make her happy, so..). Entered the Mother's Day code, said the order didn't qualify. My wife said no problem, she has another code, great - enter it: sorry, can't be combined with another offer (the one I didn't qualify for apparently). Crap, so it didn't drop the one that didn't work. No problem, incognito mode, recreated the basket, applied the new coupon - sorry, already used. Geez, do it right or don't do it at all. I actually paid full price and just said I got the discount to make her happy - we share all finances so it wasn't like I was being cheap, she just didn't want them for full price.
