Natura coupon...I tried the link, but when I select a retailer nothing happened. Tried all the ones it listed and none of them worked, tried entering a new zip and they didn't work either. And it won't let me submit my request without a chosen retailer. Going to go email them now. The World's Best Cat Litter can't be good for ferrets since it's clumping, right? If it's no good for ferrets, anyone need me to get a free bag for them? I don't have any cats. [Posted in FML 6770]
