Well, it's finally happened. A purchase I made online from a US vendor has posted to my credit card for less than the purchase amount in US dollars. The net exchange rate on the transaction (including the credit card provider's foreign exchange markup) was $0.9977 per US dollar. Compare this to the card rates of $1.0043 and $1.0008 that I experienced on our trip to Michigan.
Again, as I mentioned in my earlier post, the difference is minimal, but paying less than par is paying less than par, no matter how small the spread is.
