If you're looking to grab a BlackBerry Passport in Canada and spend the least amount possible, then Best Buy or Future Shop can save you a little bit of coin as long as you don't mind signing up for a TELUS 2-year contract. Right now, both retailers are offering a $199.99 deal until October 30th across their big box locations.
The offer was previously available for a while, then it disappeared, but now it's back again so be sure to take advantage of it. You'll have to reserve online for store pickup, stock online shows as not available. Also, some folks have had luck with getting TELUS to price match it directly but your mileage may vary on that. After taxes, it's not much of a discount from the typical $250 but any discount is better than none.
