I normally never ship out to any US Protectorates including Puerto Rico. Am I being overly cautious. Is it safe shipping out stuff to Puerto Rico? Should I include Guam? Any advice would be appreciated whether it's yay or nay.
If sent to an APO or FPO, the parcel should qualify for USPS insurance. You can tell by plugging in the Zip Code on the USPS rate calculations page.
I don't know about shipping there, but I just got this 1832 CBH from a Coin & Antique shop in San Juan, PR. Only 4 days shipping from PR to AZ via USPS.
