[quote name='ryosnk']How much was it to put up an auction? I'm thinking about selling some stuff soon and I never sold anything in ebay.[/QUOTE]
Listing fee is 25 cents, soon to be 20 cents for anything you start under a dollar. Most people usually start auctions at 99 cents. Final value fees are a precentage depending on how high the auction ends. Most likely around 4-8% at most.
Also, if you take credit card payments via paypal, and payment you get thourh paypal gets a fee taken out as well. No charge if you only accept debit and bank transfers through paypal.
Oh, and if you really want to get ambitious, stores start at $15 a month and store listing fees are only 3 cents with 8% final value fee. This is something only high volume sellers would use though.
