ebay is cheaper to purchase from, but a major PIA if you need to return something. I bought a raspberry pi (if you don't know what that is,its a small printed circiut board basically) for $20, the a-hole seller just took the circuit board and put it in a manila envelope. Notice I didn't say the envelope was padded, nor did the butt head bother to wrap it in bubble wrap, just a circuit board in a envelope. Neeedless to say the board was crap when I got it because the seller was to lazy to package it right. So I either had to jump thru hoops and bring it to the post office to send it back, or eat the $20. I ate the $20 and left some feedback for the idiot vowing never to buy from fleabay again.
