Yeah, any time they get a couple complaints about something.
I looked at the trade, it's pretty cheaply-made. And Amazon warehouses are not necessarily reputed to be climate-controlled or anything--by that I mean conditions could be quite hot or even humid, at least from what I've read--so maybe they just cooked a batch of them at one. You have to heat a book up pretty good, like in direct magnified sunlight, to warp it usually but if a book picks up excessive moisture in the cheap paper from humidity, it'll dry out warpy as well.
