Floeter Music uses the US Postal Service to deliver your books. Small orders (1-3 books) can usually be sent first class. Larger orders go media rate. Neither of those come with a guaranteed delivery date, but the post office does provide us with an estimated date. If you are in a hurry because you need specific music for a certain service, purchase the book and let us know what you need quickly, either in the order notes or by using the contact form, and we'll send you a .pdf of the song. No need to panic, no need to pay for special services. (Due to copyright laws we can only do this for books published by Floeter Music.)
