VPN works for saving money on airline tickets, getting the best price on car rental or even hotel room reservations. I often found hotel deals that costed much less from one location to another, and have saved a considerable few hundred dollars over the last couple of years using this technique I discovered through the article https://bigpricedrops.com/how-to-save-money-with-a-vpn-5-ways/ . Being smart you can save a furtune.
That link you gave also suggested hotel reservations. Have anyone tried using a VPN + booking.com on UK reservations? I still can't get over how expensive Premier Inn is now. In 2010-2019 and in 2021 (so mostly post-pandemic), I was paying around £42 to £48 a night for a room (not including extras) and the same branch is now asking for between £135 and £175 a night (again no extras), which is like 3x to 4x the post-pandemic rate! Their breakfast which you can buy as a bolt-on has always been pretty decent though and it has stayed unchanged at the £10 mark.
