You aren't crazy. I saw it too. I believe it was by baseballcardstoreca
However, I can no longer find it either. Looking at the user's posts, it is not there. I wonder if Admin removed it because it was an attempt to sell from a separate site.
I'll never quit collecting entirely, but I am downsizing. Check out my COMC store and help me thin out what I don't want so I can buy cards that I do want. See something you like? Send me a message on here, and we can knock the price down quite a bit. I'll even take a bit of a loss if it means getting you a card you really want.
