If you want to buy Lego Dimension today from a store, the best way I can work out is to use Top Cash Back to go through to Argos, add the game to the trolley and select the new Fast Track collect. Pay for it at £84.99 and then go and collect it from store. You should recieve 7.07% (£5.95) in cashback I think, bringing the overall 'cost' down to £79.04 if my maths are correct. I think this is the cheapest way of getting it now (without having to wait for delivery etc).
