Giordanos will ship frozen across country...
As for electronics. A few problems.
1. Online store incapable of handling certain shipping options by default, proprietor too dumb/lazy/cheap/busy to correctly set up automated shipping for overseas transactions.
2. Merchant account will not accept overseas transactions.
3. Available shipping option is not set up to do automated overseas transactions through online store... proprietor doesn't want to spend time shipping.
I'd imagine its a combination of these 3. Having set up a number of web stores for clients, usually a mix of the 3 keeps them from taking overseas transactions, at least in the beginning. I imagine a ship like this is someone's side project. They may just not have the time.
