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?
It is illegal in some countries such as Australia but the fines for doing this is nothing compared to the money gained for doing it.
It’s the same story in US and Canada. Illegal, but not really enforced. And when it is enforced the the penalties aren’t strong enough to be a deterrent.
