Looking for hotels at the moment. I think it's pretty common knowledge that websites like Agoda/Booking/Expedia change prices depending on how you land on their site.

If I go through Google Maps on Private Browser then I tend to see the "best" prices.

I use a cashback website - if I click through the cashback website then the prices are always much higher - with the difference more than the offered cashback.

Another vote for Trip.com - doesn't seem like they play this kind of game and the cashback offered doesn't rely on an inflated price like the rest.
