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!
This is an industry wide thing.
Some vendors detect if you are on a Mac, and the assumption is.you have money, and therefore the prices are higher
If they detect that you’re using a 19 year old ThinkPad with Arch linux, they aggressively increase the price on thigh-high rainbow socks.
