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 took a screenshot of my wishlist a few weeks before Prime Day. During Prime Day, about half of the items had Prime Day discounts but only three of them where actually cheaper. The best discounts I found were on other smaller web stores trying to compete with Amazon on Prime Day.
