Good to know, it does appear to be working.

I never saw an "official announcement" from AmEx explaining how it would work, but i do notice they charge the official exchange rate, then a refund appears later.

One very confusing part for me is that we use our AmEx card all the time in Argentina, and have been there 3 times since October.

My husband is there for the next couple of months and uses the card often

Its hard to match up transactions w/refunds though. The only way to do it (looks like) is to look at your charges for a particular day, wait until the next statement, and look for the same number of credits for the same day??

The refunds are coming from the Argentine government correct?

All it says in terms of refund is
