I think admittedly we all do this one way or the other. I've ebayed a few stock items that were stuck on the shelf and didn't want to throw it away.

But it's so few and far between and I only do it after something has sat on the shelf forever.

I normally just sell off things that I pull out of a clients system that still has some value, but the client doesn't want or care about for extra cash in the pocket. But that's also not very common.

If your doing things like what someone mentioned on here then it's only a matter of time before you get found.
