Aw shucks, I hate it when that happens. My sincere condolences. To help ease your pain I will tell you how I missed out on bike #7 (we're not counting bare frames, right?)

I responded to an ad on OfferUp for a "Road Bike good condition" about 24 hours after it was posted. A few days later I realized that the words on the seat tube were "Andre Bertin" and started pestering the seller, who was just a few blocks from my office. A week later they changed the listing to "sold" without ever getting back to me. How DARE they tease me with this potential score! I'd already brought home a $25 Montgomery Wards bike that week though, and hadn't yet introduced the pink diamondback to the garage. It was already getting crowded, but I'm still miffed about missing this one.
