Alan...you're going shotgun hunting right? It's great you're going trying to get your clothes scent free, but just remember....it's just not quite as important with a gun to be as completely scent free as a bowhunter wants to be. It's very important in bowhunting because you want them in close. I know it helps for deer down wind of you with a gun, but I just don't think it's something to get too concerned about since you can reach out and poke them at much longer distances.
Do you know if you'll be hunting on stand/doing drives yet? If you're doing drives, the scent thing doesn't really matter. Plus, the opening of shotgun season usually sends the deer into a frenzy anyway and they'll be running rampid so just shoot em as they fly by ya.
