@dirge it depends. If you go into a Warhammer store and have a go, it's completely free, but may not have all the games available for trying. Independent game stores will vary in cost and availability, but usually should be able to run you through the basics of games like Warhammer 40,000 which is the most popular one. Clubs I'm not too sure about though. As for where they are, warhammer.com has a store finder feature you can use and it usually displays official stockists too should a Warhammer store not be close enough.
