Argos have a digital dementia clock reduced from £70 to £49. Looks like they're clearing old stock as they've replaced it with a more expensive version (£80) with more features.
I was actually coming on to ask for advice on paying the 'normal' rate for those clocks (£70-80) or getting a £40 one from Amazon. But I looked at Argos this morning and saw the reduced price. It was full price earlier this week so the reduction must be recent and hopefully stock is still pretty good.
