Reasons Bookseller Crow is the best bookshop in the world:
1) A former member of Crass worked there*, and once recommended me a nice campsite in the Lake District. This replaced once having been given a bottle of Blue Nun by Jeremy Paxman as my favourite claim to fame.
2) They're offering this special promotion to anyone who pre-orders the new Dan Brown book as a gift.
Have a good weekend.
