UPDATE:

Wow - that was fast!  I received a response from Aunt Jemima already!

"We appreciate your interest in Aunt Jemima products, and I understand your interest in coupons. You'll be pleased to know that I've mailed you a $1.00 off coupon that can be used towards your next purchase. Your coupon should arrive in about a week. "
 

They go on to say their coupons are usually in newspaper inserts, magazines and in specially marked packages.    They also said to check the offers and promotions at www.quakeroats.com/products/product-offers-and-promotions.aspx. 
 

And this part was neat and made me feel special... "I've shared your interest in seeing more coupons wi th our marketing team, Jill. Thank you for your business and for inviting Aunt Jemima into your home."
