FutureShop coupon via Engagement ad

Engagement Ad leads to FBML Tab.

FBML Coupon Tab leads to FutureShop landing page with printable coupons. Is there a potential for fraud? I don't think so. You have to spend to get the deal, so just the fact that it's getting feet through the door means that if someone uses the coupon, it's worth it.  (Or that's how I see retail...)

This is just a straight advertising play though.  You don't have to be a fan (sorry, 'Like') to get the coupons, they just happen to live on that FBML Tab.  But what else could FutureShop do? (Since this promotion is only a week long?)  How about other channels?  Get an email since these customers are engaged enough to click a few times and print a coupon...  Makes sense right?

How would you improve the campaign?
