There are costs associated with everything these days and it is difficult to find a quality free service that actually is free.  There are so many hidden costs associated with nearly every service.  AuctionUSA is completely free to use for buying and selling your product.   You can choose to feature your ad for a low cost but that is completely optional.  So, give it a try and list your items for sale.  You do not have anything to lose and you just might sell your product or find a good deal in the process.
