With this request it will not give me the First-Class Mail International Global rates of $1.55.
The least expensive option it gives me is: First-Class Package International Service** for $17. I have tried allowing all international services and still does not give me letter mail.

This does work with domestic US shipments for the same item and gives me Letter Mail: $0.68.
