"We just wanted to update you that your order from TheShoeMart
Unfortunately, while our inventory originally showed that this item/size was available, it was actually already sold to another customer. We do apologize for the error and inconvenience. Thank you very much."
Thanks to @halfnhalfnhalf for sharing the 9.5D list. Supposedly the emails all go out at the same time, but I still haven't got them. Last list, I got the mail 3-4 hours after everyone started talking about it here on the forum.
