Vintage Cereal T-Shirts from General Mills
As part of the month-long exclusive with Target for vintage cereal box designs, General Mills is also giving away retro T-shirts. All you need to do is enter the codes from five proof-of-purchase labels at cerealwear.com and you get a free shirt.
Alternatively, you can just buy a T-shirt on that website for only five bucks! Note that there's a five shirt per order per day limit. We've got our eyes on the Helvetica-looking Cocoa Puffs.
