You've got a ten quid discount! How did you wangle that?! I paid £73.90 ( inc. duty, VAT & "brokerage") collected by the UPS guy on delivery. Some difference between UPS (that the first batch seemed have been sent by) and DHL you seem to have been allocated? Mind you I get the sense that they all make it up as they go along, e.g. I never got any text telling me in advance how much it would be - a man in brown shorts just turned up who demanded money with menaces!
I've (hopefully) got a second one on the way (in the same way as beerking has been notified, Involve say this order is complete, but I've oddly not received any tracking details yet) - will be interesting to see what random amount I'm charged when it turns up this time!
