To be honest i have to confess to being a bit cheecky with this (although i am glad to see that others are benifitting from it) My summer stuff has not sold at all since I listed it so I have been looking at other products I can list in one of my unused stores. Now if 2 or 3 people came on here saying they wanted stationary for instance then i would be more inclined to look at listing that.
On the other side of that as has already happened somebody might have looked for a certain item not found it and bought elsewhere when it was sat waiting to be listed under 50 other things.
