I put 5 of those and 5 pouches in my cart and was waiting till pay day to get them, on the 25th you sent me a discount coupon that said it was good till Dec 2nd, I went to pay for my order on the 27th and the coupon wouldnt work, when I sent a message about it I got a response saying the coupon doesnt work with the 10% black friday promotion, these items were the same price now as they were a week ago when I put them in my shopping cart and it was only 2 days after you sent me the coupon that I tried to use it, whats the deal?
