Around these parts its about 10 dollars a bag. You ever tried sweet feed. Its close to the same price and our deer seem to prefer it over corn. We only feed preseason because it is illegal to hunt over food here but until October 1st we lay it out thick. We did a little "experiment" with corn and sweet feed last year with two feeders in a food plot. They would go snif around the corn first then go to the sweetfeed and only if the feeder with sweetfeed was empty would they go back to the corn.
i havent bought a bag of corn the last few years but it is over 8 bucks ..i have 2 acers of standing corn,,,on the food plot they are going to have to eat it off the cob , the old fashion way
here in Nebraska it's $9.50 per 50 pound bag. we have 8 feeders going and put 3 bags a week in them. here's a pic of what's eating the corn though, almost makes it worth it.
