I sent a deposit and later the balance due to a researcher in Ukraine
(researcher was used by multiple individual members of a JewishGen group
researching in given towns) using Moneygram, which I used at a machine
located in a CVS. Each time I paid the researcher $225 cash, which was sent
as U.S. dollars, and fee was $15 U.S. There is a reference number provided
on receipt at CVS that I transmitted in an e-mail message to the person in
Ukraine, and he then used the reference number in Ukraine to receive the
money. Money was transferred with no problem.
Hope this helps.
