Probably anyone interested in Doctor Who will know that three issues of the Radio Times will have packets of stickers 'free' inside - the current issue (i.e. the one covering programmes from today 28th April) has the second of the three. There is also a free sticker album (normal price £1.49) is you send off a large SAE to an address given in the magazine. However, if you buy the Radio Times from WH Smith, you should get the album free, though you may have to ask. My local branch (Basildon) had a big display stand with copies of the album bearing a sticker indicating that it was free with the Radio Times (unfortunately, I had already bought my copy elsewhere but if they still have stocks left next week, I'll be getting a copy there!)
I suspect it's High Street branches only, but it's worth taking a look, especially if you (or, ahem, your children ) like Doctor Who has have been collectingthe stickers!
