Sears and Kmart offer 2,000 Shop Your Way Reward points (1,000 points from each site, a total of $2 value) for free when you view your Sears and Kmart Local Ads. (Click the "LocalAd Points Giveaway" banner on each page; not a member? It's free to join.) That's $2 for free and the best offer we could find, although we saw $3 in points three weeks ago. Deal ends May 30.
Note: Points can be redeemed from June 1 to June 7.
