What confounds me is that people think a return policy is there for them to do test drives, it’s not!! You return, you should have to pay for it, period end of story. Abuse of these policies is what drives prices up.
But then how do you demo a piece of gear from an online retailer? Go to a brick and mortar, try it out and then buy from online? Sweetwater will even send gear to people, better customers, for you to try and maybe you'll buy it, maybe you won't. The retailers keep track of abuse of the policies and if you read their terms and conditions they usually will state that they reserve the right to limit returns on persons that are abusing the return policy. Free returns is how online makes more sales. Have you gone to a store, tried an amp or a guitar, played it for twenty minutes and then walked out without purchasing because it wasn't what you wanted? Did you pay for the electricity used? the HVAC used? the salespersons salary? Of course not. Free returns are the online analog of a test drive in store. It's far better than going to a brick and mortar for a test drive and then buying it online.
