$0.22 Profit on a Dan Dooley Euro Trade

When I was in Ireland last week, the rental car company charged my credit card €58.65 for gas on 3/25, which would be refunded at the end of the week provided we return the car with a full tank of gas. I returned the car with a full tank of gas on 3/31, so €58.65 was refunded to my credit card. American Express charged me $79.86 for the €58.65 on 3/25 and refunded me $80.08 for the €58.65 on 3/31 - a profit of $0.22.

Ireland is a beautiful and expensive country. I’ll post some pictures of the trip later.
