awww, you're just a youngster then, lol :-D
Customs open maybe one in 50 parcels, it's a VAT lottery of sorts. It helps if you're getting stuff in second hand boxes, and if the forms are filled in at all.
I had one batch of car parts that had been openned and labelled as 'no value' ... which I'd paid over $1000 for ...
Oh and if you ever bring in a car you pay 10% import tax on the vehicle + shipping cost, then you pay VAT on the total!!!
