Ordering from Amazon anonymously

I haven’t tested it myself but I heard it’s best to build up account reputation by first aging the account a bit, then buy a cheap digital item like a song, and then age the account further before buying a physical item. Even then some people get banned after several successful purchases if they never end up adding a card attached to someones identity. Privacy.com is probably less suspicious than a prepaid card or gift card but it has the caveats of not being totally anonymous and only available in the USA.
