You get 50 free listings per month. In addition, they are running all free listings through tomorrow. That is in addition to your 50. If you were to exhaust your free listings, you would pay an insertion fee. You can click on the fees link on your left hand column but for a $5.00 starting price, it wouldn't be more than $.25 or so.... It is the final value fees that will kill you. 9% from ebay and 3% from Paypal.
