A note on international shipping : where applicable, when USPS First Class International shipping is selected you will be automatically upgraded to FedEx International Connect Plus (4-8 day transit time typically). Some locations are prohibitively expensive for this service (4-5 times higher than average) and as such will still receive standard USPS or Ebay International delivery. Please contact me with me any questions about transit time.
