I used to make my own rubs for almost 15 years.
Partly due to the volume required, as well as I thought I cold make a better product myself, and partly because I felt that some of the rubs were over-priced.
I too recently purchased "Simply Marvelous" rubs and found them to be the best commercial rubs I had ever tried. My only regret was that I hadn't tried them earlier. I would have abandoned the making of my own rubs long ago if I had known these rubs were perfectly balanced with flavors.

You'll love the Simply Marvelous Spicy Apple Rub, and Simply Marvelous Sweet & Spicy Rub, and Simply Marvelous Cherry Rub. Let me know how you like the other rubs so I can give them a try.
