There is a reason you are getting no sales on QS.  There has been a big issue there for about a month now, descriptions are not showing.  I first reported it in early September then 30+ other sellers jumped in and said the same thing.  Apparently if you are running adblocker then your descriptions can't be seen.  Turn adblocker off (for me anyway) and I can see my descriptions again.  Only problem is how will the buyers know that?  They just think I am too lazy to type a description?  

The first thread posted on the QS forum was deleted by admin, the next one (still running now) shows the problem still isn't fixed.  However they did personally email me and ask for more details (previously their standard answer was "we can't replicate the problem/so it doesn't exist".  They are at least working on it at the moment (so they tell me in the latest email).

QS was good a while ago, I was selling even par with my ebay store, and doing better because there were no fees (except paypal).  Hopefully QS will lift their game and take on the opportunity they have been given on a silver platter by ebay - let's face it they don't want most of us anyway.
