Heres what I've used...and had deer walk almost within reach of me...

- Wash clothes in plain water unless really dirty....then only non-scented soap.

- Hang outside to dry.
- Shower with baking soda or no scent soap.The super market has a no-name liquid that I use and is only a couple bucks for a litre of it.
- Store clothes in a plastic garbage bag,dusting them with baking soda.
- Prior to hunting,mix in some cedar or pine branches into the bag.
- Use apple juice(or similar)for a extra cover scent
- Hunt the wind

This will cost you less than 10 bucks for the entire season.Hope this helps....
