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?
This is a tale as old as time. We did this in the late 90s at an office supply store. Every Sunday night changing price tags “ooh guess there will be a sale on resume paper in the next few weeks”. 1-4 weeks out we would increase prices on some items just to lower them back when the ad came out.
