Thanks for posting John

I checked my invoice too. The breakdown is:

111 point check Pounds172.50 (VATable)
2 year warranty Pounds2292.31 (VAT exempt)
Sub-total Pounds2464.81
VAT (on 111 point check only) Pounds30.19
Total Pounds2495

So you've been charged much less on the warranty element itself. My OPC said that the amount charged for the warranty is set for the whole of the UK by PCGB. So I am not sure how OPC Wilmslow has been able to charge so much less for it. Anyway, you've got it cheaper so you're smiling
