Here’s how the unusual offer works:

Only on days that the Montreal Canadiens are playing a playoff game, you can go to any BestBuy or BestBuy Mobile outlet – but only in the Montreal area – and pick up an iPhone 4 for $99 on a three-year contract with Virgin Mobile.  The longer the Canadiens stay in the Playoffs, the longer the offer continues.

Oh, there’s one other catch: You’ll need to download this coupon and bring it with you when you roll into one of their stores for the offer.

Full details here.

But wait there’s more…

Turns out Montrealers aren’t the only ones who get to bask in the iPhone Playoff celebration. The same offer is being made in British Columbia. Grab the coupon and head in to any BestBuy or BestBuy Mobile location anywhere in B.C. This offer is good for (you guessed it) any day that the Canucks are playing a playoff game.
