All of my music (with the exception of the items under the "Physical CD" tab) is sold digitally. (In other words, what you're buying today isn't so much "print music" as the rights "to print" a number of copies of the relevant PDF documents.)
Almost immediately after your purchase, my site will send you a link to download these PDF files. You agree to print and maintain no more than the purchased quantity of copies of any PDF(s) received. If you later determine that you need more copies than originally purchased, you agree to return to the site to purchase the needed copies, or to make other payment arrangements with me directly.
