The t-shirt deal of the day over at RIPT Apparel is the Harry Potter-themed “Horcrux Collectors Club.”

The tee, by artist Matt Dearden (totally love his stuff), went on sale at RIPT today, Wednesday, December 29, 2010, 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 t-shirt is available in men’s and women’s sizes in black for $10 each. Kids sizes are $15 (Boys, Girls, and Toddler, all black); Onesies are $18 (in black). You can also get the design on a Hoodie for $38 (in black in Men/Unisex sizes).

The design features the Horcruxes used in the Harry Potter series by Lord Voldemort in his effort to achieve immortality. I don’t want to go into further detail, in case you haven’t read all the books or seen the last few movies. But, if you’re a Harry Potter fan, then you’ll totally go for this shirt design.
