D C.

As mentioned above - they sell damaged and already used musical instruments.
I bought an audio card that came in a used box full of paper. The box with the sound card was wrapped in bubble wrap. The box itself was already open, and there were someone's prints and damage on the card. You cannot exchange for a new one, you can only make a return. But if you make a return, they will charge you shipping fee + something else. I bought this item at Stupid Deal. I thought I won $100. Ha! I broke down hard! To return it back, you need to pay more than half the cost. There is no point in returning.This store is owned by the guitar center. I guess they are in the same situation.
SWEETWATER charge shipping fee too if you will make a return. But I've asked them about damage or used gear. They said we need some proof if you have some damage,if item arrived damaged - we don't charge shipping fee. I don't trust to all of them, but sweet water looks nice, then Musician Enemy
