Under my "social media" folder in Gmail, I only save messages from famous people and stuff that is unresolved. I recently noticed an "unresolved" thread of Twitter messages from two years ago. It was the first time I'd ever interacted with a corporation through Twitter. And the last. Notice the dates on the messages. I never received a coupon, so I replied again, exactly two years later.
Okay, I might get a free bag of Kitten Chow out of this, or maybe not. Not that I need Kitten Chow anyway, since the cats are all adults. I think I'd originally bought Kitten Chow for Gogo, to get her strength up in her old age. Several days later, I received an envelope from Purina, with three coupons! But they were all for $1 off a bag of any of their dry cat food products. On the back they say, "Limit one coupon per specified item(s) purchased." Great. I'd have to buy three bags of Cat Chow to save any money at all. But I really wouldn't save any money, because I normally buy store brand cat food that's way cheaper. Thanks, Purina.
