You place a auction and then when the auction ends you get all of the credits from the final ending bid. The more credits you have the more stuff you can find and bid on using the credits to win some worthy items. It's like eBay but simpler. Least that's how I see it lol
You will get more bids if you offer free shipping & you can get a small priority box @ your po & ship this for around 5.00 & you will get higher bids also , Good luck I will be bidding if it is free shipping
