I made a booking a while ago for a rental in Poland. At the time it reserved for ~800 EUR. Today I was looking at the reservation and it says it will be ~800 PLN. Right now 1 EUR = ~4.25 PLN, so that's a 75%+ discount. I "modified" the reservation by changing nothing and I got an email with the 800 PLN price again. Will Hertz honour this "new" price, or will I still be charged in EUR in the end?
