Here's how to get a free Lean Cuisine entrée! You'll need Facebook for this freebie.
Go to the Facebook page of Lean Cuisine Canada, click "like." Then go to the "reap the rewards" tab on the left, click "I'm in," log in to the app.
Once 20,000 fans have clicked the "I'm in" button, Lean Cuisine released their coupons for free food. Click the "free Lean Cuisine coupon" towards the bottom of the promotional page, and click "get your coupon now."
It says the coupons are available for a limited time only, and they're one per person. It's for 1 free Lean Cuisine of your choice.
When I did it, the coupon was valid between 11th and 17th January 2012.
Get it fast in case they expire soon! Thanks again to shuwent for emailing this in.
