This was certainly £126 yesterday and is £99 today.
I imagine it is due to the immenent release of the DC31. I know people have sourced this item for less from Asda but for those that haven't it is under a 100 quid here.
(Infact, just picked one up from a local Currys, using the pricematch + 10% of the difference discount). So you will be able to get one at £96 quid, should you have stock in a local Argos to match against).
