Hugh Fearnley-Whittingstall just e-mailed me (ok, maybe it wasn't Himself). He will swap you some of his very own seeds for some of your hard-earned cash. He has the following to offer IF you buy one of his books:
1 free pack of Costa Romanesque courgette seeds
1 free pack of Blauhilde French climbing bean
1 free pack of Uchiki Kuri squash.

This is the link if you're interested: http://shop.rivercottage.net/rcv2/shop/springseeds.jsp

Personally I'm not bothered: I've got my beans and courgettes sorted, and I'm not that keen on squashes generally, but I thought it was worth a look if you were in the market for a H F-W book anyway.
