Hey all - a while back, Roman and I hinted at a special bonus for fans who pre-order copies of the book, and the time has come: click this link to get your challenge coin!. The coins are entirely free for US buyers (international readers will have to pay a flat shipping and handling fee so we don't lose too much money on this!). As someone who was a 99pi fan before joining the show, I love our challenge coins, and I think we did a really good job on this one - I was frankly giddy when my 'proof' coin showed up in the mail. Hope you like it! -= Kurt

Update: As of around 5 PM PT 8/30 we're down to handful of fully free coins for US buyers. We'll be updating the page shortly when they're out, but we still have a stock of globally available ones for people (in the US or around the world) - the difference is these ones will require a flat S&H fee.
