The t-shirt deal of the day over at RIPT Apparel is the Star Wars Starbucks mash-up “Darth Roast Coffee.”

The tee, by artist J Christian Reed, went on sale at RIPT today, Wednesday, January 26, 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 takes Star Wars villain Darth Vader and puts him in the center of a Starbucks-like logo for his own brand of coffee. The Imperial logo is also incorporated into the design.
