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!
Yep. Dynamic pricing.
Other people have reported it with travel sites when looking at flights, you get different prices on a Mac vs windows.
Vendors of any ilk would love to be able to adjust prices per customer.
I need to try with my user agent set to a Chromebook. Maybe I’ll even get a discount.
