I've gotten several emails from Santas whose plans have gone somewhat awry, so fear not, anyone who hasn't yet received their gift.
Santas, if your tracking, or your estimate of time in transit says it should have arrived, let me know, and we'll investigate. If you gave a gift certificate, via email, let me know, via pm, and we'll check on it. Often such emails go straight to a spam folder. Likewise, if you're waiting, check you spam folder for an unseen gc email.
