100% satisfaction guaranteed huh? Yeah right. There will be no clear refund policy. While legit stores offer exchanges or refunds within 30 or so days (or sometimes, not even offer refunds if they're total G's), plenty of counterfeit sites will claim to offer some sort of return policy, but go completely radio silent when you try to actually utilize it. Also, any company who claims to refund your money if you haven't received your product in a month isn't worth doing business with in the first place.
8. Refund policy is totally unclear
