UPDATE: It looks like Teefury changed their shirt deal for the day, but you can still get “Brightest Witch of Her Age” from their “Gallery” section here for $18. The shirt deal for today is for two Adventure Time mash-ups: one with E.T., the other with Labyrinth.

The $11 t-shirt deal of the day over at TeeFury today is a Harry Potter-inspired shirt called “Brightest Witch of Her Age” by MeganLara.

The sale began at Teefury today, Thursday, February 27, 2014, at midnight EST, and will continue for 24 hours from then, and once it’s over, it will not be sold on the site for $11 anymore, though it will continue into the next day for $14 (look for the After Hours bar at the top).

The t-shirt deal of the day over at RIPT Apparel today is a mash-up of Doctor Who and Space Invaders called “Invader Who.”

The tee, by artist Megan Lara, is on sale at RIPT only for today, Monday January 3, 2011 until tonight at midnight CST. Once the time is up, the shirt will no longer be available at the site.

The t-shirt is available in both men’s and women’s sizes in Black for $10. Kids sizes are $15 (Boys, Girls & Toddlers in Black); Onesies are $18 (in Black). You can also get the design on a Hoodie for $38 (in Men/Unisex sizes in Black).

The design takes the pixel aliens from the 1980’s arcade game Space Invaders and puts them together with a pixeled Dalek from Doctor Who.
