He is trying to tell you that your sale items are posted in an inappropriate place. That is the purpose of Flea Market. To keep "for sale" items out of bike specific threads.

Those cases are only worth what some one will pay. Your opinion really does not matter. You can move it back to Flea Market, you can find another media to sell it on or you can keep them. What you should not be doing is bitching about it here.
Don't agree with that, we will just sit back and watch what happens.
