I bought one of these from a Tesco store in Swansea on the weekend. Price should have been £379, but it came through the till as £349.
On Tesco-Direct (linked) the price is £379 down from an original price of £599.

There is a similar model on sale at eBuyer for £349, but that is inferior - it only has a Sempron processor and Intel graphics.
I've set this up, so far it looks very good. The only negatives are the poor quality peripherals and monitor.
This is a misprice in store at the checkout, so it may not work for everyone.
