We strive to ship all orders within 2 business days. Shipping costs are based on 8vo size books (about 8"x5") weighing 2.0 pounds. If your book order contains more than one volume or is heavy or oversized, we may contact you to let you know if extra shipping is required. While most Media Mail shipments in the continental USA arrive in a timely fashion--in some cases media mail can take 2-3 weeks for delivery--sometimes longer. All of our shipments come with tracking numbers.
**Standard Shipping ** in the USA is via USPS Media Mail: $5.65 for the first book & $3.25 each additional book. We will contact you if your parcel requires additional postage.
Priority Shipping in the USA is via USPS Priority Mail or by UPS: $12.95 for the first book if your book will fit in a Flat Rate Mailer, and $20.50 for each additional book (Heavy & oversize parcel charges may apply and we will contact you if additional postage is required).
International Shipping is via USPS Priority Mail or by UPS International: rates start at $42.00 via a Priority Flat Rate Envelope, depending on the destination. If your book will not fit in a flat rate envelope, rates will be higher. Posted international rates are subject to change based on destination and weight--we will contact you if your parcel requires additional postage.
