Sometimes you have to keep listing it. When I sold my 10-22, I ended up giving it away for $550 on Ebay because $650 wasn't getting me anywhere. It never helps when other sellers with lesser quality were selling theirs for $500. I got the same BS offers through my email begging me to let it go for $400. I threw in the hood, a Hoya UV filter and free shipping to get extra bites. It worked out and now I have my new MacBook.
