It's like a lot of things that common sense can make up for. You can make it work without spending a dime or blow a month's worth of wages buying products if you choose to.
If I wasn't careful about how I entered and left the woods or making noise and moving around unnecessarily, not being stealthy, I wouldn't see many deer. Had plenty of deer downwind of me or walking on the trail I entered and not run off although movement and sound have gotten me busted.
I've been in the habit of using soaps and detergents that are unscented while keeping my hunting clothes in plastic bags and totes away from the house. If things get wet I hang them to dry before storing them again.
