I used that program to buy my license this year, my elk tag only cost me $80.00. I did not have to deal with any fine print at all, it all went very smooth. I was in Montana when I purchased my tag, I'm not sure if you would have to be present or not. The person at the Fish and Game office told me that I did not have to be present. I used my Dad for my family member, he has lived in MT his entire life.
My Montana elk tag has costed me thousands over the last ten years, but I always pay it so I can hunt with my dad and brother. I is nice that it was not such a hit on the pocket book this year.
