> if the wallet is custodial I recommend using a self custodial wallet. > even with phoenix teh issuer still maps the merchant to your IP Phoenix supports tor so you can hide your IP. Also, with a physical merchant, you are typically at *their* IP address when you make your purchase. > how do u handle the shipping address It depends on where I am, since I travel a lot. There are lots of small businesses who offer "On Demand Package Receiving Services," which means you can specify their address as a shipping destination for packages, and then pay a per-use service fee when you pick up your package, with no monthly rate required. Sometimes I use those. Consider looking for such a business in your local area and use them if they exist. If not, consider starting one in your local area, so that you can become your own customer as well as provide services to others. If neither of those is an option for you, consider renting an airbnb for use as a shipping destination, or ask a friend or neighbor or place of employment if you can ship stuff to their address and then pick it up.
