Great sale at Lulu
Thanks to Denise at Let's Play Math I learned about this great sale at Lulu. Take $20 off any order of $20 or more. Valid through 11/30/10 in the US only. Wow! Many books are print-on-demand and you'll have to pay for shipping. But some, like this one from my hero James Tanton, are free with the coupon.
