Where to buy dried corn to make corn meal?

I guess the title says it all. I have a Grain Mill, and I want to try grinding corn meal. Where would I go to find dried corn?

whole foods and other natural food places usually have bulk corn or they can order it. the hull on popcorn is too thick though it is tempting to try.

I picked up a 10 lb of bag of a really cool blue corn online a couple years ago had purple tacos and corn bread

for small batches I have used popcorn...however, you need to sift it after you grind the corn.

I used a hand grinder twice on popcorn, that there was some real hard work.

I wait till after thanksgiviing then acquire those displays still on the shelf


Here's one of the better deals on bulk dried corn

Statement retracted...........I just purchased the Walmart cracked corn and they have a new brand and supplier. This feed corn is nasty, dirty, and smells bad.

I have purchased a lot of corn and wheat for grinding from Pleasant Hill Grain:
