Yep – use a rewards or ff points credit card if that option is open.
Some places only take paypal – so I use my PP when that’s the case.
If I’m making a foreign transaction (purchase or rental deposit in a foreign currency) then I use my Cap One credit card to get the better exchange rate.
It’s all about reducing transaction costs, increasing rewards. Whatever costs me the least.
