I came in to make an exchange from a forced sale of something at the last GNC I was at. The salesman here was very helpful and recommended products in alignment with what I was looking for. However, when making the exchange he would not honor the $10 off coupon I used on my original purchase less than a week ago. He said he did not have the code. I've worked in sales for years and I know that isn't right. There's always a way to honor the coupon!! It's not like I came in without it and just asked to honor it - my receipt specifically showed it. That's the reason for my lower star rating.
