I personally don't, but I'm sure it can be done. Here is just some things you can do:
1. Use a fake name.
2. Use an email that isn't personally identifiable.
3. Get yourself a P.O. Box and have everything sent there (for when you order packages on Amazon) (you can still be identified offline, as there's no way to get a P.O. Box nowadays without actual proof of identification and residency)
> USPS has good deals.. I'm paying about $5/month for a small box (purchase of an entire year) ... as a web app developer with a business, I really didn't want my home address to be known, so this worked for me to at least keep my address somewhat anonymous, but they are all mostly inexpensive, and even if it doesn't fit into your mailbox, they'll just hold it at the Post Office for you with a notice on your mailbox to pick it up at the counter
4. You will have to buy gift cards at Walmart so you can purchase at Amazon and other websites.
