I've recently been shopping for a Roomba i7, which up through yesterday was on sale for $538.99 at Amazon, as well as Best Buy and all the other major online retailers I could find. I put it in my shopping cart but didn't buy it while shopping around, reading reviews, Pelican threads (always helpful on stuff like this), etc.

Sometime yesterday, when I looked in the cart again, Amazon let me know that there had been a price increase. There sure had--up to $699.00! I checked the other retailers, and sure enough they had all lock stepped their way up to Amazon's price. I don't know how quickly they made the adjustments, but I bet it was pretty much automatic. Probably driven by an algorithm, but I don't know. Anyone know how this all works?
