The t-shirt deal of the day over at RIPT Apparel is the Iron Man – Star Wars mash-up called “The Invincible Iron Bot.”

The tee, by artist Gadget WK, went on sale at RIPT today, Wednesday, March 9, 2011, at midnight CST, and will continue for 24 hours from then, and once it’s over, it will not be sold on the site anymore.

The design mashes up Star Wars droid C-3PO with Marvel superhero Iron Man.
