re: Ebay or Amazon?

Amazon - Every day stuff, stuff I'm willing to pay full/normal price for, stuff I want quickly.

EBay- I really only use Ebay when I have something specific I want and don't want to pay full price or its hard to find it elsewhere. For example, I want a specific, not-that-popular pair of Olukai flip flops in a certain color - I'll see if it's on Ebay. People stuck with a not popular pair of flip flops in size 13 just have limited options to unload them.

Stuff like that, or clothes (Amazon doesn't have any good deals on Orvis, Peter Millar, etc.) can be good on Ebay, especially if you find it from an individual seller. I mean, if your mom bought you a specific Peter Millar blazer for Christmas in a specific size, you're going to be limited in selling it if you can't return it for some reason. Good chance you can get that on a pretty deep discount if you know what you want.

Downsides to Ebay are sorting through junk and scoping out reliable sellers. But it's pretty easy if you have common sense.
