Get 2 Free Sheldon Books!

From now until Nov 1st, the complete Sheldon book collection is on sale!

I’m pretty sure we’ve never had an all-in-one price this low… but it’s pretty dang sweet. You’ll save $36 when you get all the books — essentially getting two of the books for free!

I have done a LOT of math in my life, and I’ve never had math that felt this right. ….It just feels right.🙂

Snag the entire collection right now!
