It's not online, but when we went in today they had signs up saying if you spend over £75 on lego, you get a free £20 gift card for use after Christmas.
there are a few sets around that mark, I thought it was good value - just in case anyone is interested!
Plus they had the set we wanted reduced to less than Argos (who reserved it for me but didn't get the delivery in on time).
It wasn't even that busy in TRus either.
