How to ensure introductory price if waiting on SIMs to arrive

The sime usually comes very fast one or two day max so as long as you activate it by the 11th your are safe

Simply, basically and sadly.... you can't.
.

As a reference point... I ordered one friday night (April 5) and received it in Quebec City by Canada Post today (April 9).
.
So you need to activate them ASAP when you received them, preferably before the 12....

Please comme back and tell us how it went.

Where are you located ? If you are in Montreal you should be good, I received mine within 2 business days.
