This one is still pretty expensive in stores and as a bonus I'm throwing in the hardcover limited edition guide after 5000 credits. It's worth bidding!
Between having a photo, verifying your phone, and replying to comments, you have done everything you should, which is a lot more than most first time sellers do. Some people on Listia are just a little whiny and often don't know what they are talking about, especially new members, such as the people who previously commented on your auction.
Good luck with your auction and I am sure you will get over 5000 credits.
