My apologies for going off topic for a second, but is it well-known that Amazon seems to use Uber-esque surge pricing?! I (like apparently a lot of people) went to Amazon to buy the book cited as soon as I saw it (and it looks like a great book!). There were eight copies left in stock, and I bought it for $62.69.[1] When I went back to Amazon a few minutes later (following someone else's link), there was only one copy left in stock, and it was listed for $98.60.[2] With my apologies again for being off-topic, is this a known phenomenon?

Anyway, thanks for seconding their recommendation of the book; I'm looking forward to reading it -- and glad I saved the 35 clams!
