This has to be one of the Lego Bargains of the month. Lego Harry Potter Knight Bus for £7.50 at Sainsburys Swadlincote, not sure if national. I thought this was a bargain when I first saw it in this store at £15 a couple of months ago. They had at least 8 on the shelf after I bought a couple. Lots of other Lego reductions in store too, but this seemed to be the best.
