My girl was looking for a dress for Halloween. Yesterday she found one on Amazon for € 35 and put it in the cart, but did not buy it. Today she looked it up again and it was € 50 so she asked me to look it up with my phone with my Amazon account - it turned out to be € 23 for me, less than half of what it’s for her!
I haven’t experienced that, but I used to do my amazon purchases at the end of the month until I noticed all the prices get raised around that time. So now I shop without rhythm to not attract the price inflation worm
