I did mail as well, BUT I did not receive the standard "thank you for your Target order" email. I can see them in my account, but it just says "order created," and the charge is still pending on my Discover card. Strange.
I received an email from Target this morning saying my Target Gift Card order has been delayed. The new estimated delivery date is now 12/12/2014 - 12/16/2014.
Did anyone else get this? Not really afraid that they're gonna run out of Target Gift Cards, but just slightly annoyed. Perhaps next time I'll just get the online gift cards instead.
