Best Western Rewards is currently running a promotion where you can “Like” their facebook page and participate in a little game where can win up to 100,000 points. Personally, I won 100 (which is the minimum). Once the game has finished, you can refer friends to the game for another 100 points. Fortunately, I have a friend on facebook that also does points/miles so it was easy to refer one friend and get 200 points out of the deal. Not bad for 30 seconds of effort. T&C say 2-4 weeks for the points to post.
