Agreed on this Global Shipping Program. The whole bloody thing is a scam. Sometimes packages get through without customs charges and I suspect that they just keep the charges.
Amazon US is so much better. They charge me the fee in advance but then reimburse it if there wasn't any cost incurred.
Can you buy video games from Amazon US though? Last time I tried I was barred from buying one even after a lengthy negotiation with the seller. The Amazon webpage showed me a list of stuff that I was forbidden to buy from the US, and used videogames was amongst them. (along with food, alcohol, guns, etc.)
