As an Alaskan that shops eBay now and again, I'm frustrated with this exclusive statement. I run into this twice... where I really wanted an item, and the seller wouldn't budge one iota. I was willing to make up or cover the difference in shipping, ship to a verified USPS address, and most every other reason, but the sellers wouldn't budge.
I chalk it up to general ignorance and an unwillingness to do business. Their loss... I can go elsewhere or bide my time.
