Be Aware that Postal rates increased in May, 2007. U.S. and International Shipments are going to feel the effect. Most are quoted as I see necessary.
INTERNATIONAL - Recently the rates of U.S. Postal Service changed. The biggest effect is to Global Shipments.
Noted - a 4 Pound item that can fit in a Global Priority envelope is now $11.00. Measurement is vital factor.
Not all Countries participate. Effective Immediately if you live outside U.S. the $11.00 amount will apply - not all auctions reflect this amount because of time necessary to correct all.
The items that do not qualify NEED TO ASK for specific rates - they have increased also per location. Best if you can ask before bidding - it might effect your desires.
