Hi Mr Scunner
I did as you suggested and got the 8% off £399. The promotion codes didn't work but I got £10 off with ZG561 for being a new customer. Also a deduction because good ole Gordon dropped VAT rates and they hadn't put that into the price advertized (odd that). So I calculate the net cost after all this is £360 (plus £5 Quidco fee). Not bad, but I wish I had ordered it last week when AppliancesOnline had it on offer for £341 - now £447.
So thank you old chap, please accept a knighthood. Shall now write to Quidco to apologize and tell them to ignore my previous email.
Colwyn
