Like others I have buyers wishing to buy from USA but unable to do so. I have called Ebay 3 times and so have they but keep being told all is in order and they can buy. No-one seems to know what the problem is . Any suggestions?
eBay's Global Shipping does tend to block some specific items from being sent to the US. The alternative is to opt out of GS in your postage preferences and relist the item with direct postage to the US.
