In order to have better results with this auction, please add more details regarding your item. Your auction is missing a description or picture. These two things will go a long way in instilling confidence in potential bidders. We also highly recommend that you include pictures of the actual item that is being auctioned, (not just use stock photos from the manufacturer). For higher valued items, please include a notecard or piece of paper with your Listia username in one of the pictures of the actual item. This will also reduce the number of questions that your bidders will ask, and most importantly, you`ll get the best results with your auction.
Thanks for making these changes and good luck with your auction!
