GIN means GET IT NOW. After you become a member and sell enough items, you get the option to add to your listing a GIN(GET IT NOW) Which means you of course set the starting Bid for the auction, then you may add the Gin Option which if u have a specific Amount of credits you would take and instead of wait on the auction you can set the GIN amount at what credit amount the item is worth to you. Then someone can Hit the GIN button an it ends the auction right then. Then you follow the rest of the steps like normal, Get address,send item...
Thank you for letting me know this. the next thing i put on here i will see if i have that option because i have not really done to many auctions before so i did not know about that option. thank you for letting me know.
