In case you didn't know...

How would you not know ? Not knowing really who 'you'  might be...but if 'you' are here then 'you' almost certainly know that the Beatles tome is retailing at 30 squids at Waterstones but, wait for it, wait for it - it is an astonishingly cheap 18 squidos at W H Smith but ... wait for it, wait for it.....you can get 2 for  mere 22 squideroonies (getting bored of this). But would you really want two copies ? Yes...but hold on.... family shouting in ear that not supposed to buy two of the same book ?! What do you mean, family ? Cannot compute ? Of course I need two copies; one for the dust-free-air-conditioned-Beatles-bookcase-in-kids-free-study and one for the coffee table !!! Are you sure you are my kids ?
