At 11:00am, got notification to say that the order for the 4 parts, including a clutch sleeve assembly, has been shipped and another from Royal Mail to say that they had received the package.
Cost of P&P via first class delivery was £4.20+VAT.
I'm not sure where the "Rimmers' excessive P&P charges" views originate as I would not class £4.20 given the size of the order as excessive. In fact, quite a bargain!
