How much to ship flat rate USPS priority to Guam?

I'm about to ship a flat rate box out with priority shipping and was wondering how much shipping would be from the U.S to Guam? I heard that all flat rate priority shipping costs the same within the U.S but I'm not sure about Guam. If anyone could, please help!

1. Shipping via USPS Priority flat-rate boxes to Guam will cost the same as within the U.S. However, it may take a bit longer to reach the recipient because Guam is overseas. Flat-rate priority boxes range from $9.80 to $12.95 for the larger box. Guam is considered domestic mail with USPS because it is a U.S. territory. MANY postal clerks don't know this so be sure to write the zip code and they'll eventually realize it.
