pay me amex bill with 2315 phyiscal cash in Ramot eshkol. They are going to transfer it to my bank acct for this fee....
If you have a Leumi Bank in the USA, can you deposit USD cash into it in Israel?
If you can do that then you should consider opening such an account in NY (if the fees are worth it), depositing cash in Israel, and paying it by drafting that account.
