According to FB Joe:
Several of the fantastic t-shirts at Design by Humans are on sale for only $12! They’re trying to clear out some designs that they’re never going to reprint, so this will be your last chance ever to get them!
Combine this with the cheaper shipping options (or did that just about to non-US orders?) and we’ve got a bargain on our hands! The cheap tees are on the front page of designbyhumans.com under the title ‘Clothes Out’.
