Yes, the cut is down to £180 but you could find it easily for £150.
Irrelevant. This price drop will allow retailers even greater flexibility for their price drops. So whatever discount you were able to get before, you'll get a better discount now.
That's true. But, I doubt tthey'll be any vicious cuts below what you could already get it for on the week we are talking about. In the future we could, but that isn't important when we are talking about the first 4 days (?) of sales really post price cut.
