It's worth considering joining The Wine Society. It's a co-operative with a one-off fee of £40 for a share and there are no commitments after that. I've been a member for ages now (I'm sure it was only a quid to join back then) - I get a mixed case for £85 every other month through their Wine Without Fuss scheme and the wine is always decent at the very least.
The best one I've had recently was the Baccolo Apassimento Rosso Veneto which is made in a similar way to that described by Hibsbollah a few posts back - £6.95 a bottle and just a bit too drinkable.
