Rice Bran from the feed store is the way to go.
Bingo. It's just basically rice bran so why anybody would pay the extra money because C'mere Deer is stamped on the bag is beyond me. And neither will perform any kind of miracle. It's just bait. So make sure baiting is legal where you live if you plan to hunt near it. If I were gonna put out bait I'd just use corn. It's cheaper, much more weather proof, and deer love it.
On a funny side note, I actually got temporarily banned from the Archerytalk forums for poor mouthing C'mere Deer in the above fashion. LOL! That is how far up the butt of celebrities and corporate Sponsor's that place has become. Sad.
