I just received a letter from World's Best Cat Litter.

"The current program will be changing as of September 30, 2007. If you're currently saving nine UPC codes for free loyalty coupons for our litter, that's fantastic. Just be sure to get your UPC codes to us before September 30th.

If you haven't collected all nine be then, don't worry. The new Rewards Program will launch on October 1, 3007."

There's more info, but if you don't have the right quantity to turn in, be sure to ask for the latest coupon information where you purchase the World's Best Cat Litter.
