I also found out from my coworker that her own daughter discovered their Amazon purchase history and this discovery led to another discovery that spoiled something sacred to kids. Yeah, that kinda sacred.

So if you are worried about a potential discovery of items purchased, be they gifts for someone else or just something no one else ever needs to see and you have a shared Amazon account, then follow these instructions to protect yourself. It's not a perfect method, but it is another layer of protection.
