Like Mark G' I have a subscription to HORNBY, and every now and then I'll buy one of the others from W H Smith if there's something interesting on the cover or a DVD for our son.
Arthur F's comment " Surely the whole point of WH Smith is that you don't have to *buy* magazines to read them... " is true for most mag's but many now have a plastic cover. The people in our local W H Smith can be a pain ..... standing in the way whilst I try to get a mag to BUY, so I send my boy in, he ask's them once to move then he just gives a push.
