Payment Methods:
Payment is between buyer/seller.


** Auction - Warehouse **

http://www.auction-warehouse.com/

Payment Methods:
Payment is between buyer/seller


Those are the decent auction sites which serve as alternatives to
Ebay.  The ones listed as having payment between the buyer/seller
means that the site serves as a listing agent but does not handle
finances.  It is up to the buyer and seller to negotiate the terms of
payment, be it paypal, check, money order, etc.

If you have any questions or need anything cleared up, please request
a clarification before rating my answer and I will be happy to help.

Pay Pal Shops is another great resource to find sellers that accept
Pay Pal, try this link http://www.paypal.com   Pay Pal is owned by
Ebay & Ebay is the dominate force in auctions.  Visit me online at

I would just add ePier (www.epier.com) to the list of competitors.  It
is much, much smaller than eBay, but does get *some* activity.

I think more and more you will see personal auctions in more of a peer
to peer, free usage:
