@vincent @jack - Here's the basic info: https://www.amazon.com/gp/help/customer/display.html?ie=UTF8&nodeId=200444180 If you sign in and go to "Your Account," then click on "Prime," Then "See All Your Prim Benefits," Then down at the bottom under "Other Benefits" is a link for "Share Your Prime Benefits" which shoudl take to to where you can add another adult to share your Prime Membership. They also have a "household" thing now which might do the same thing, but that's not how we set it up years ago, and I don't know what, if anythign is different about doing the sharing through a "household."
