If you love all things Discovery Store—and what’s not to love?—today’s the day to get over there, because they’re having some of their lowest prices of the year.

Use coupon code SHOP10 for an additional 10% off, or code AFFSHIP75 for free shipping on $75+ (shipping starts at $4.95, otherwise).

I recommend all things Mythbusters, personally, but they really have something for everyone.
