We always donate at least one through Share the Harvest, often times more, depending upon how many we shoot. We donated three last year.
The processing place picks up some of the cost in collaboration with the state of Missouri, up to a point. Basic rule is that if you don't want to pay all the processing costs yourself donate early before state funds run out. This usually means before gun season gets more than a few days old.
To me its a pretty worthwhile charity, and you definately know what your donation is being used for.
