Oh, sorry, this doesn't have anything to do with the fact I added the item to the cart. So I'm not complaining about expecting the cart price to be held, just that the prices seem to fluctuate kind of randomly and without notice.

I can understand if the product were listed in the market and fluctuates depending on seller. I can understand if the price a few days ago was promotional. Neither of those was the case.

The price when I added it to the cart was what I thought was Amazon's own "regular" price. Guaranteed to be the lowest price. Today it's almost $23 more. Still guaranteed to be the lowest.

Using that history site shows that the price jumps between the two amounts every couple of months. I would have pulled the trigger on Friday had I known it was about to go up. It just wouldn't have been as convenient.
