Shipping
I usually and prefer to ship UPS ground/insured. UPS air/insured if necessary and or desired.
USPS (United States Postal Service) is available, and is sometimes used domestically for shipping, and more often than not is used for international shipping.
Take note: USPS has lost packages of mine shipping internationally.
Normally, except as otherwise agreed upon, The buyer pays all shipping costs. These are determined before shipping.
