I purchased vitamins from GNC store in my area and the sales person didn't give me a receipt for my purchase. I find that out when I got home so I went the following day to return the product after I read bad reviews and horror stories here but to my surprise the same salesperson who happened to be the manager said their return policy is to have the receipt or I can get store credit! I am so upset and angry because he simply made his $$ and made sure to keep my receipt so I can't return the product. I will call GNC headquarters and I hope I get somewhere with them to refund my money! read full review »
