I have recently joined a well-known coffee club and expect to get a nice coffee maker along with my first shipment of coffees. Of course, I'll have to keep an eye on my membership so that I get things done in a timely manner. I don't want to receive coffees I haven't actually chosen.
This holds true if you've joined a movie club, book club, or wine club. Make the minimum number of selections and make sure you get your order returned on time so you aren't sent what they select for you. Have the subscription costs deducted automatically so you won't be late with the payments. Keep the club membership for as long as you feel you need it and the minimum purchases are made, then discontinue it if everything hasn't turned out as you'd hoped.
Since I am a coffee drinker, I think I'll be a member for quite awhile!
