from what my old man has said, customes can add VAT and Duty on even if they think you've not paid for it (gift, etc. RE: last order Beaker
)
In that instance you tell them that yes it's a gift, but only has a value of say $15/20. They wont make enough money out of you to really bother.
Me and Beaker ordered about $600 worth of stuff, it arrived and they wanted to know how much it was worth and what it was for. Once i'd spoken to the lady and confirmed in a fax it was a free girf and only worth $20, the box arrived next morning by UPS.
