I live in Canada and have ordered from. It has been a few years so don't recall whether or not they email a notification when your package is ready to ship, and along with that don't remember exactly how long it took to get here. I wouldn't expect anything to arrive in under 2 weeks, while 3 weeks is more reasonable.
You can also leave them a message through their contact page, and include your order # with your query:
