Reids have a buy one get one free sale on at the minute, but to be honest I'm holding out until January when I imagine there'll be a lot of knock down prices. You should think about doing the same if you can wait.
One thing I've been told about the January sales is that a number of places hold the stuff for you for up to 6 months, so even if you're not ready to move in there and then, it could still suit you. Obviously, not all outlets do this, but worth asking.
