Pretty much off topic, but the opening paragraph of this article highlights what I think is a little-known benefit of Prime membership. The author notes that "sharing an Amazon Prime account with loved ones is surprisingly intimate" but it doesn't have to be if you use Amazon Household:

"Sharing benefits through Amazon Household requires both adults to link their accounts in an Amazon Household and agree to share payment methods. Each adult keeps their personal account while sharing those benefits at no additional cost."[1]

It's limited to two adults (plus teens), so not a solution for all cases.
