ThinkGeek's Huge Pi Day Sale: 31.4 Percent Off Everything


For math nerds across the globe, March 14 is known as Pi Day. For deal hunters, however, it's a day to score deals on some of our favorite gadgets.

ThinkGeek, for instance, is taking 31.4 percent off sitewide via coupon code "PIDAY19". Even better, the coupon stacks with sale items in ThinkGeek's clearance section. That's one of the best coupons we've seen from ThinkGeek. (Although it doesn't top its 50 percent off coupon, which we last saw on Black Friday).

A few noteworthy deals include: 

Shipping for most items starts at $8.95 or you can have your items shipped to your nearest ThinkGeek store for just $7.95. Alternatively, you can get free shipping on orders of $50 or more.

ThinkGeek's sale ends today.
