I TOTALLY agree with slobby!!!!! I did this aprox. oe year ago for a total charge of just over 25 bucks. Got 200 lbs of mineral. The deer still dig at that spot...as of a month a ago.

I've also used deer cocaine.....yes it works, and serves it's purpose. Had MUCH better luck with the powder apposed to the liquid. However...for the money you can't beat doing it yourself. You can also ad yeast to the mix and it will help in the digestion for the deer.
