While eBay is far and away the largest online auction site today, it’s not the only one. You can use several other online auctions, many of which feature lower fees than you pay to eBay. (Some even let you list for free!)
Know, however, that these sites have a lot—and I mean a lot—fewer members than does eBay. Fewer members means fewer potential buyers, and fewer potential buyers typically means fewer sales and lower selling prices. That might not be the case in all categories, of course, and a lower sales rate might be offset by a lower fee structure. You’ll need to evaluate the potential of these sites personally, to see if they offer anything for you.
