Welcome to listia! Until you get I think it's 9 auctions ended with winner and positive feedback from the winner, you can't use Gin on your items. Plus it cost you credits. I know this because I'm still new to listia. You should get verified, you will get more bids.I fanned you and I'm watching this auction. I hope you do well.
I should have checked your wall before commenting. Click on your auction, then click edit. On the lower left side of edit page, there is a short sentence about setting a starting bid or something like that. It's not in bold lettering the sentence is light or gray looking. Click on it and you can set GIN if you have no bids on your item yet. I hope this helps.
