Homemade Sloppy Joe mix

I went into the grocery store today. I think the prices are raising daily. Each time I go to get an item the price seems outrageously high.
Take for instance Manwich Sloppy Joe mix in the can. Today for a Large can (enough to do 2 pounds of hamburger - they wanted $3.75 for one can! There was no way I was paying that - I knew all I had to do was google "Homemade sloppy joe mix" and I would have a recipe that wouldn't cost me an arm and leg.

Here is one I found at RecipeLink.com
