I don't need the digital services but if I get into a family account would everyone see what everyone else is buying? I don't know what my kids buy and I don't want to.
[i think this answers my question]
When you live with a family member who has Prime, it's easy to just ask for their login information and take advantage of those benefits without paying for an extra membership. The trade-off is the loss of privacy.
Everyone in my family uses my brother's account when we need to use Prime. It's convenient and keeps the cost of membership low, but it also means we can all see what everyone is looking at and buying. Furthermore, confirmation and shipping emails are sent to my brother and have to be forwarded to the appropriate recipient.
It turns out we've been overlooking a key feature that would help relieve these problems and help us regain control of our shopping: Amazon Household.
Amazon Household lets each adult keep his or her personal account while sharing Prime benefits at no additional cost. Here's how it works:
You'll need two adults (ages 18 and over) each with their own Amazon account. One must have a Prime membership.
Both adults must agree to share credit and debit cards associated with your Amazon accounts. Both accounts will retain their current payment methods, but you'll each be able to see and use each other's credit and debit cards.
You can set up content you would like to share within your Household. This includes current and future purchases. After setup, you will still be able to manage or change your shared content. Shareable content includes apps and games, audiobooks, and eBooks, so you can have a whole family library accessible to you if you'd like. Here's what that setup looks like:

Of course, you can't share the great Prime benefits with anyone if no one in the household has a membership in the first place. From speedy shipping and delivery policies to digital content access and exclusive member pricing, a Prime membership will be an indispensable tool for the whole family.
