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!
yeah and I’ve done a lot of chatting about amazon products online at reddit, forums, etc over the last 20 years or whatever and never once seen people get different prices on the same amazon link.
There are definitely different prices when I’m logged in vs when I’m not. My wife sends me a links to products, and I usually open any link in incognito windows. Several times I was not seeing the same price as her. Opening the same link on my account would show the same price.
