Since its inception, Amazon Prime has allowed you to invite 4 other people to share the main Prime benefit, 2 day shipping on all orders, without any additional cost.
In that system each of the 5 members maintained unique accounts that made Prime splitting between strangers very easy.
Effective immediately you can now share Prime between 2 adults and 4 kids only. And just to make sure of that, all of your credit card information will be shared between all accounts. Obviously not something you’ll want to do with a complete stranger!
If you already have household accounts under the old system, they are grandfathered for now. But you won’t be able to add new ones, so think twice before removing them. Household accounts under the old system will not have access to each others credit card information.
If you opt into the new system and invite another adult to your account you will now be able to share all Prime benefits, including Prime Instant Video, Kindle Owners’ Lending Library, and Prime Early Access. Amazon Mom members will also be able to share 20% off diapers and 15% off baby registry completion. Apps & Games, Books, and Audiobooks can be shared if you choose to share them. But once you opt into the new system, both accounts will be able to make orders with any credit cards that are saved in either account.
