Just draw them out of the ATM while over there. The FX rate VISA give you is a way better than the bank.
- Use a debit not a credit card
- Get a good chunk at each withdrawal as you’ll be charged a transaction fee (still way less than what the bank steal in the FX margins).
- If the ATM offers to do the FX conversion at a fixed rate, say no. That’s just a US bank robbing you instead of a Irish one.
If you really need cash the GPO in Limerick should have some on hand, they only do US & UK so they’d want to. No bank is going to have $1,500 sitting in a drawer. They might have $300/400 though from people selling them. I’d ring around.
