No, there are no fees, on AudioFlea’s end, for buying items on our classifieds. You may be subject to tax depending on the state that the seller resides in.
At this point, AudioFlea does not have auctions for listings. If this is a feature you would like added in the future, let us know by adding a comment on the Feedback Area on the forum.
If you have a specific question about an item listed on AudioFlea, you can contact the seller directly from the product page. There is a button to the right hand side that says “Contact Seller” which will prompt a message to be opened up in your My Messages section of your My Account.
