Shipping Terms:

U.S. BUYERS. Standard -- Most orders can be shipped by USPS Media Mail within the continental U.S. for the standard charge regardless of weight. Expedited -- Items which fit in the Flat Rate Envelope (about 6" x 9") can usually be sent by Priority Mail for $10.00; in that case we will automatically reduce the shipping charge for an expedited order when the order is processed. Items which fit in one of the Medium Flat Rate Boxes can ship for the standard expedited charge, regardless of weight.

INTERNATIONAL BUYERS. If you have questions about shipping charges for a specific item or items, please ask. Shipping is based on the use of the Global Priority Flat Rate Envelope. Heavier or larger items may incur additional charges; we will contact you if this is the case.
