In case you missed them, Kellogg's released 5 codes over Halloween, each worth 100 points. So enter them all and score 500 free Kellogg's Family Rewards points!
I'm not sure when they expire, but I expect it's soon.
This is very similar to their earlier “meatless snack” quiz, which also gave 500 free points. I still proclaim eating snacks while taking snack quizzes should earn you bonus points, but Kellogg's continues to ignore my daily emails. Oh well, I guess it's just 500 free points and the rest of this beef jerky!
You may not see the 500 points added to your account automatically, but no worries. The fine print says points are awarded within 72 hours.
In addition to the free points, taking this quiz also resets Kellogg's clock to losing your points.
