While shopping HyVee* today, I noticed a full end cap of Halls Cough Drops marked at 3/$3 or $1 each. Use the $1/1 coupon here and grab yours for free!
Because this is not an advertised price, I am not sure if you will find them in all stores. However wanted to give you a heads up so you can keep a look out at your store as well. Leave a comment if you find them.
*49th & Louise is where I found them today
