Yesterday I went to Gnc to get my collagen and the large can was sold out and they only had 1 left of the small can so I purchased it and was given a coupon for $5 off a purchase of $30 or more but the coupon expires today so I went back there to ask if I could order the large can and pay for it in store today and have it either sent to me or I would pick it up at the store now the collagen is more expensive here but with the coupon it will cost the same as Amazon when it came time to pay the man told me I could not pay cash
