Definitely.
"How much is too much" depends on how poor you are.
At my most flush I've regularly spent £30-£40 per bottle and try loads of different types, but nowadays I have to settle for supermarket prices, so I've found a couple of nice ones in the £7-£10 range that I buy either one or the other of pretty much all the time... a Bordeaux in the Co-Op called Vieux Manoir and a Cotes De Rhone in ASDA called Vinsobres.

I will 1oo% try these 2 mate and I'll let you know what I think.
Where were you buying your 30-40 pound bottles by the way? Just somewhere like Magestic?
