good point if your not sure on the regs around your area then you wont be hunting longAbout the easiest and least expensive product I know of is red trace mineral salt which farmers add to cow feed. It has minerals and molassas in it which makes it sweet and attractive to animals. It was pretty cheep and sold in 50 lb bags. Makes a great mineral lick and you just mix it with surrounding dirt. The deer will dig down as it leaches into the soil. Check your game laws before using any attractants for hunting.
