You will not be required to submit a payment for your classified ad until you try to publish it for public view. At that time, you can click on the tab that reads "PayPal Publish" and submit your payment via PayPal. Once that payment has been made, there will be no further charges for your ad. You may edit or refine your ad as many times as you like and not be charged. The ad will remain published for a period of one month, or until someone has agreed to accept your item - whichever comes first. If your item has not sold by then, you may choose to have your ad deleted, or you may pay another $5 to place the ad for another month.
