I had a Superstone one for several years that finally cracked itself up a couple of weeks ago. No idea why, it was just during normal oven heating.
Anyway, this was a perfect Wootoff moment for me. Sitting on the subway this morning, I was looking at my iPod Touch (not from Woot) using my Freedompop WiFi hotspot (yes from Woot). I saw this item with 14% remaining, figured what the heck, and a minute later, one pizza stone the richer, all on the 7 train. Sadly, that was the high point of my commute, as the train quickly became uncharacteristically sluggish (due to the proverbial “system delays”), and my total trip took more than double the usual time. But at least I’m getting a new pizza stone!!!
