Amazon Prime Days ran on July 16th and 17th (at least here, in Canada).
This price jump happened a day before and ended two days later, but this item was “on sale” during those two Prime Days.
I’ve been seeing this scam far too often, especially with food items. Why isn’t this illegal yet?
I do score some very good deals on Amazon, but I also use a browser plug-in that lets me get a notification once my desired price has been reached. I always look at the historical charts, though. Some items are constantly going up and down in price. At least we have that option with Amazon, and not so much with our local grocery stores :(
