Domestic shipping is done mostly with USPS. Larger orders are shipped  occassionally with UPS.
All international orders are shipped using UPS due to extremely legthy delivery times and unreliability of USPS.

International Buyers – Please Note: Import duties, taxes and charges are not included in the item price or shipping charges. These charges are the buyer's responsibility. Please check with your country's customs office to determine what these additional costs will be prior to purchase.  These charges are normally collected by the delivering freight (shipping) company or when you pick the item up – do not confuse them for additional shipping charges. I do not mark merchandise values below value or mark items as "gifts" - US and International government regulations prohibit such behavior.
