Amazon's done a lot to perk up its Prime shipping subscription over the years, most recently adding a complimentary streaming music service for members. This got us wondering: Are Prime subscribers using all those perks? We're calling all Prime members to take our latest survey. (It's short!) We want to know if you've made use of Amazon Prime's benefits, and if so, whether you subscribe to similar services elsewhere. Click here to take our poll now! Update: Thanks for the input, everyone! The poll is now closed, and we'll be sharing all this great data with you soon.
