£37 for customs charges on £110 seems way to steep. I get stuff from the usa all the time and customs is usually something like £8 handling fee and £6 import tax ect and for something around the value of £110 I would have thought £20 max :?
I once got a customs bill for £1600 on one item I bought, think it was a guitar, but rang them up and they said it was a mistake and re issued me a new bill, so I would ring them up just to check as they do make mistakes now and again.
Back to your obi wan

its a lovely figure and I think I paid £80 all up for my loose complete one from the states about a year ago if that helps
