Large companies like Lysol make many different kinds of products and they want you to buy all of them. The best way for them to get you to buy something is to give you an incentive to go out and buy it. One of the ways that they will often allow you to save money like this is by offering you a sample of the new product attached to something you are already buying. They will also include Lysol coupons on the package that you can use whenever you are ready to buy the new product so that they will get you hooked on using it.
