Have you used amazon subscribe and save? What you described is basically how it works. You're agreeing to auto-buy at whatever price amazon sets on that day. The only exception when you first set up a subscription, in which case the first delivery's price is locked in.

Amazon will tell you the price 7 days before it auto-renews and then jack the price up 100x three days before it renews?

The price will fluctuate, but this is on another level, and deceptive since they had already stated what the price would be.

Yeah probably? [edit: no, see below]

You go on amazon 7 days before renewal, check your subscriptions, see it's $10. 7 days later it's no longer sold by amazon and the only other seller selling it is a scalper that charges $30. The only difference the order of magnitude, not whether price changes can happen.

No, that's not what happens. They lock in a price when they alert you to the upcoming delivery round.

I sometimes get "item available" cancelations for this reason. The items are always available, just not at that price.
