When your order ships you will receive a separate email providing you with a tracking number to track your order. Sometimes this email gets sorted into spam or promotions folders so be sure to take a look in there if it feels like you have been waiting a little too long.
You can also log into your account and click on the order in question to see the status.
*Please note that sometimes the tracking can take a day or two to be updated by the carrier. If it looks like its not moving, chances are its on its way!
