I'm with Commander - £4.20 for a pint of Harveys isn't that bad. To put it in perspective, London prices are pretty much around the £5 a pint mark as Commander says. If it's below that you're on a winner. If it's below £4, then you're in a shit pub.
Something's been bugging me about this news story - has any considered the impact that 15 kids has had on his wife. Must be a bit loose down there now, Shirley?

very interesting read. Doesn't really come as a surprise due to the aggressive capitalism which is prevalent in the food and supermarket industry, but playing with peoples lives...
