Well, I was reading a review on a supplement like I always do before I but it. Anyways there was a guy that said he works at GNC that if you take the supplement back within thirty days even if its almost gone and you give a legitament reason why you want you money back (Like it made me sick, it wasn't effective Blah blah blah) They will give you a full refund. I then looked at GNC's policy online and it said the same thing. Has anyone ever done this? The guy also said its basically a way to get free supplements. What do you think about this??
