I'm not exactly sure what they cost, but for the sake of conversation...lets say they cost $10. I would recommend taking that $10 bill and wading it into the smallest ball you possibly can. Take this balled up $10 and throw it in the lake/pond/river wherever you are fishing in the general direction of where you want to attract the fish. Without a doubt, this method has about the same effect as the above mentioned "bait ball", AND it saves you a trip from the store!
