This site sells ebooks. You download them. I won’t physically mail them, let alone bring them to your house. Why the heck do I request your address and phone number in the checkout process?
If you won’t get meatspace mail from me, I don’t care what your address says. I only care that your payment goes through.
If you need an invoice for business or tax purposes, use your correct address. You can print invoices from your account.
