Rice is dirt cheap and low margin. The sort of people who eat rice everyday are also the sort of people who buy a 40lbs bag that lasts for months because rice doesn't go bad. Also, my (stereotypical) impression of people who cook rice everyday is that they are not rich and willing to spend money of this type of luxury. My guess is that rice is one of the last products that automatic restocking makes economic sense for.
