I'm only a seller.
I have found that buying stuff (unless it's rare) is a total waste. I can get it at the store or online anywhere else cheaper.
But selling is great. No risk.
As a test, I found an old computer in the dumpster. I sold each part. Made $71 off a computer that was older then me.
Fact is.. it's amazing what people will buy and pay. But buying off eBay... nah. Not unless I can't get it anywhere else.
Here's a tip.. look for common mis-spellings. You'd be surprised how many people sell something for really cheap but spell the item wrong. Hence, they get no bids. You bid, you win and get it dirt cheap. It's happened before.
