$10 for how much? A 10lb bucket?
It's the salt they're after, not the flavors. Once it soaks into the ground it's dirt flavored, and they still eat it. I've got a salt lick that is 6ft wide and 2 ft deep, all dug out by the deer... always fresh tracks on it. The deer after the salt, plain and simple. Anything else that's in with the salt serves one of two purposes; mineral additives to increase antler growth and general health, and gimmicky crap to part hunters from their money.
