Okay, now I sort of think I see what the problem with this is. Usually, after the item sold, on the All Selling page, directly under the item it says:
eBay note: International sale thru Global Shipping Program.
The HDMI cable, and now a game I sold today does not have that under the listing. Did I somehow accidentally not qualify for the Global Shipping Program or not authorize the item to sell under the Global Shipping Program? I took a look at the rules of the Global Shipping Program and noticed something. It says that:
You must have a US seller rating of standard or above to qualify for the Global Shipping Program.
Is that new? I've been below standard for several months now and I've still been allowed to sell with the Global Shipping Program.
