The AARP Kellogg's MIR is the only one I'm aware of. Did you write down the date when you mailed it? When sending in rebates, I always write down the date it was mailed, what product the rebate is for, $ of the rebate, date I received the rebate, etc.
You cannot do a kindness too soon, because you never know how soon it will be too late.
