You may be able to purchase another one if is sent directly by the seller rather than through the global shipping program. I have no idea if that type of thing is restricted by our government but the GSP often restricts items that 'might' be restricted versus items that 'are' restricted.
For example, some types of wood can't be exported so the GSP often restricts guitars regardless of the type of wood. I've heard that sometimes they restrict certain types of older radios, but other times they don't. So it isn't always consistent.
They don't actually throw out the item, they have someone resell it for them for the same price that you paid but it is only shipped domestically. If you see it on ebay you might be able to repurchase it and have it sent to a reshipper that isn't associated with eBay or Pitney Bowes.
