There was a news item the other day confirming what we know tgat travel sites will offer higher prices when a search is made from an Apple product. Don’t forget that for almost any website now you click a button agreeing to cooking as well — “to send you relevant advertising” — among other things. I use Amazon a lot, prices are good, but sometimes it’s obvious that the best price offered is a load of crap. Clear cookies and search for it on Google maybe using word Amazon and get a better price. “Targeted advertising” is also used to try to influence how you vote, location, spending patterns, biases from searches that sort of stuff. Using a vpn all the time works but blocks quite a lot of sites of course so not always practical. Worth it for bigger purchases though.
