A similar thing happened to me as a seller. I saw that one of my old textbooks was selling for a nice price, so I listed it along with two other used copies. I priced it $1 cheaper than the lowest price offered, but within an hour both sellers had changed their prices to $.01 and $.02 cheaper than mine. I reduced it two times more by $1, and each time they beat my price by a cent or two. So what I did was reduce my p…
The opposite scenario (sort of), from Michael Lewis' Liar's Poker: One day earlier in his career Dall was in the market to buy (borrow) 50 million dollars. He checked around and found the money market was 4 per cent-4.25 per cent, which meant he could buy (borrow) at 4.25 per cent or sell (lend) at 4 per cent. When he actually tried to buy 50 million dollars at 4.25 per cent, however, the market moved to 4.25 per cen…
In calculus terms, it would be like taking a derivative of the Amazon marketplace and operating on different rules than most or all buyers and sellers on the marketplace.
The trick is minimizing your risk and making sure to adhere to Amazon's terms. [Does the scenario in the grandparent comment go against Amazon's terms I wonder?]

Automatic pricing is super common these days, even on more expensive things than books. I'm actually working on a startup called shopobot.com that wants to help people use the volatility to their advantage. We see rapid $50-100 swings on things like SLRs, so it's actually pretty significant. Ironically our site is down right now because we're based on Amazon's web services. Karma? :)
That actually sounds pretty awesome. Didn't some of those CSE's like MySimon used to have a graph of pricing over time as well? Any way I can get an invite code for Shopobot?
