Some ebay basics, listing fees are on a sliding scale based on initial price. If you know you have something that is popular and will get multiple bids, I start those items at 99 cents. That cuts the listing fee to a bare minimum. If it is something that won't get much interest, then start it at the minimum you would accept. You can easily gauge interest by searching completed history.

I am not up on the new rules yet (they just started).

Don't bother with a reserve, that just costs you more too. Use one of the free picture posting services like slide.com or auctiva.com. Thats another way to save on the listing fees. Accept paypal or personal check, hold the check long enough for the item to clear. Money orders and cashiers checks just cost more money for buyers and are subject to fraud anyway.

I tend to leave my money in paypal, as I end up spending it myself. I have cashed out a few times. Get your paypal verified, it makes transferring funds out easier, and is reassuring to buyers.

I avoid international shipping, other than Canada. You can easily estimate Canada postage on the USPS web site.

Of course, if you don't have any feedback on ebay, that will scare away some bidders and cost you some. Remember, 99% of the risk is taken by buyers, not the sellers.
