i use any natural items that are close to my stands. if im hunting around pines i will break off branchs and rub the sap and needles on and around me and then hang them on the stand. same with acorns i will smash them and add water and let it sit for a day. there are all kinds of things you can use and they seem to work better then some of the products they sell. (one i do use is the scent waffers if i dont have anything else they have work very well for me.)
