I had a slightly similar experience...
Many moons ago, I bought the DE SDK from Amiga, and whilst browsing their site, I added a couple of Amiga T-shirts.
All was fine until the courier person turned up demanding the payment of the VAT and import duties, and other stuff - which came to nearly half of what I'd paid in the first place! Argh! :-(
Not happy - and it was all down to the t-shirts (hehe - isn't it always!?)
