just to add to wot others have said - Mojo is a realy stand up guy; and never one to profit from fellow members off this board.
other thing to consider - is the shippin from UK is gonna be expensive. CHeck out Royal Mail website or Parcel force if u like. I would say $40 is actually abt right; esp.ly if its includes tracking and insurance. If its any consolation - the Royal Mail charges us Brits an arm and a leg even for domestic shippin.
I typically pay USD $40 for a helmet, shipped from US.
