HERE to get a coupon for Mom's Best Oatmeal. They will send you an email to confirm your email address and when you do you will be brought to a page to print the coupon. Make sure to press the back button on your browser to print extras. It let me print 6 of these coupons instead of the regular 2 you can usually print with bricks coupons!
They sell these at Walmart and SuperOne for sure, and they are usually $1-$1.25.
