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?
Also illegal in the EU, when posting a “sale” the price compared to must be the lowest price the outlet had for the product in the previous 30 days. So unless they want to increase the price for over 30 days, this trick isn’t going to fly.
