 And I can't think of a better way to spend $45 than everyone's favorite fill-a-flat sale. Grab a cardboard flat, fill it with an incredible mix of K&W's fabulous annuals, perennials, and veggies with values over $100. This is a great deal for anyone. Fill a flat and fill your world with flowers. From K&W Greenery, Highway 14, Janesville. K&W Greenery. Your car.
