All of our orders are shipped using USPS or FedEx. We use realtime standard retail pricing. In the US if your package is over 13 oz. the shipping changes to US Postal Service Priority or FedEx. For international orders your package can stay at the USPS first class rate until you get to 3 1/2 lbs. After that you will need to choose USPS Priority or FedEx international option. If tracking shows that the package was delivered and you did not get the package, please contact your postal office for more information.
