I ordered a book with pick up in store using a 15% off coupon I'd received in my email only to have Barnes & noble cancel it, do I tried to reorder it & my coupon was rejected saying I'd already used it on my previous order. I contacted customer service about it because why should I not be able to pay the amount I'd already agreed upon. They keep asking me to send them my order number & coupon code do they can research the problem. Now they haven't contacted me since so I wrote them again only to be ignored. I'll be ordering my book on Amazon now.
