Started playing around on eBay a while back when a college rommate moved out and left alot of stuff behind. We have always been on real good terms, so I didn't think anything of it when he told me to keep whatever he left. That pretty mush got the ball rolling on the whole online auction thing.
Payment policy
I, as well as most eBayers, prefer PayPal. It may cost a slight amount but it is lightning fast and gets things sent very, very quickly.
Shipping information
I don't have a hard and fast rule about shipping. I usually prefer USPS Priority Mail because it is the fastest way to get things where they need to be.
Return policy
Not ever had to deal with this, so not exactly sure what to put here. I'll keep my fingers crossed that I don't have to figure out my policy about this.
