READER FRANCES JENSEN emails that Amazon has discontinued its price-protection policy. That’s never been a big deal to me, but it matters to a lot of Amazon customers. I wonder what’s behind that change? Does Amazon expect a lot of price-drops in coming months? I would have bet on inflation myself, but they’re probably in a better position than me to forecast these things.

UPDATE: Reader Jay Dean writes: “Sometimes when a company gets big enough, in market share or otherwise, it doesn’t feel the need to keep up with all the extra bells and whistles that it needed to attract that market share to begin with. Could Amazon be the new doctor who dumps the girlfriend that stuck with him all the way through med school?” Gosh, I hope not.
