Why can you no longer find the refills for the Lysol Ready Brush I have the brush and now cannot get the refills for it?

I contacted Lysol and they are no longer making this product and haven't for the past 18 months or more. I, too, am stuck with a product that I liked and can no longer use. they are sending me a coupon for another product. I just wish they would buy back the old one and recycle it or something.
