Thanks - Used parcel to go in the past but not for wheels. They quote £28+vat for 4 wheels as seperate packages which will need some sort of protection.
But this lot seem to be a good deal at the moment.

Same price inc VAT as one package - Can get wheels put on a pallet so v.good value this one, and not worth the petrol or time to do myself.
