Yeah, I listed them both at $400 BIN fixed listings to see what kind of interest I generated. I got plenty of views, but not a single offer. I decided to relist them as $.99 NR auctions, as I knew they would do really well. When altering the listing style, I forgot to remove the BIN option on the Mario tin sign. A watcher from the original listing probably figured the auction would go nuts and jumped on the BIN. The neon sign auctioned for just under $400, if I remember correctly.
If you want to hear another one (which I realize isn't actually the case), I recently picked up a high-end vintage cassette deck from the swap meet for $45 a few weeks ago. It's currently going for a several hundred dollars with two days remaining. Ebay never ceases to amaze me.
