@Leo Patrick Wisted You can certainly open a line at any of our stores.  One of the advantages of ordering online is that the Connection Fee ($50) is waived since you are doing all the work with regards to your new account. 

Basically no. Either you order online and wait. 

Or you setup in store for a fee and get it right away. 

Buying a sim in store will not activate that sim in your new account. If you ask the store to do this for you they will charge you the fee anyways.
