I read about this generous offer in the local paper.
There was an article that stated that Milano pizza would be giving away free pizza in Ottawa when you ordered through the website:
Better hurry as there is a limit of 200 pizzas per Tuesday!
If this offer seems too good to be true, Milano Pizza is also donating $1 for each free pizza ordered to the Ottawa food bank through this promotion.
So looks like you better order quite quickly to take advantage of this.
