address admin area book button buttons buy buyer buyers check checkbox checkout choices code copy digital item mailing main option page paypal physical prompted requested required seller send shipping standard tax

In my seller admin area, one of my choices for buttons is the BUY NOW button option. I use PayPal Standard. Although my main item is a digital book, I would still like to get the name and mailing address of the buyer, in case I need to send a physical copy, as some buyers have requested.

I know I can specify "shipping address" as a required option if I set up a PayPal button directly, but what do I do to get the mailing address when I use the the e-junkie code for a BUY NOW button off that page?

Even for BUY NOW buttons, when you check "shipping" or "tax" checkbox, they will be prompted for shipping address on the checkout page.
