I hope you're cool with 50 free Kellogg's Rewards points because that's all I've got right now. Unless you want this half-empty pack of gum? Or how about a cold cup of coffee? No? Just the points then. REDANDGREENPTS4U is what you're looking for and you've got until 12/31 to redeem it.
Also thanks to all the loyal Hiffers who keep commenting on our list of active free Kellogg's codes. I often find these codes first there!
