I was the winning bidder on those auctions. I was fully refunded, but I am very disappointed not to have the items.
I wish I could say this was a one-off, but incidents like this are increasing. For international shipping, the local post office (Royal Mail in the UK) seems to be the only choice for an international package.
Even for non-military/firearms items, eBay's Global Shipping Program is shockingly expensive. At least they make up for it be being slower than any other shipper.
