One wine I buy in quantity when in France (Calais Hypermarkets) is
J P Chenet.
It retails at about £1.50 (about $2.75) per bottle there and about £4 ($7.25) in the UK. Despite the very low price, the flavour is very good and quality consistent. It is instantly recognisable by its 'bent neck' bottle - says a lot for the marketing dept as well.
Judging from the link above it is available in the US. I'd be interested to hear the cost of it over there and, if anyone has tried it, what they think of it.
