 I'm a member. I find it to be worthwhile because I shop on Amazon very frequently. I get cash back at Whole Foods. And then there's the free streaming music, the movies, the free Kindle book every month. And so if you are a user of some or all of those benefits, that membership can really pay off. But in my opinion, you shouldn't have more than one of those retail memberships. Pick the one that serves you the best and stick with that and shop with that retailer regularly.
