why my snackdown T-shirt hasn't been dispathced?

Can someone of codechef staff told me why my T-shirt hasn’t been dispatched…

You got any mail for address and stuff? If not, then is that section updated in your profile?

Dont hesitate, bombard them with mails for your goodies. They themselves insist that, cause sometimes delays happen. They take some time to reply, but the mail is seen/read by them immediately. (They tend to fix the issue before replying, so that kind of explains the delay.)
