I've bought lots of things on ebay.. So I've been asked about it...

Single biggest advice I give.

Approach buying on ebay like being at an auction, or gambling. Never bid/gamble what you can't afford to loose.

You never know what you're going to get is really worth it. You never know if you're even going to get what you purchase. So.. like I said. Don't bid/gamble what you can't afford to loose.

I've been burnt a couple times, but for the most part the sellers have been good.
