About Us Midwest Municipal Supply was founded in 1989 by Jerry Buck. We started out with 2 trucks and $100,000 in inventory. Since then, a lot has happened. Our delivery fleet has grown to 7 trucks, our inventory has grown to over $2.5 million, our staff has tripled, and we set new sales records every year. We are the largest single store operation in the St. Louis metro area. Our goal is to save you time and money. We make sure the order is right the first time. Our large inventory enables us to limit backorders. Our hands on approach helps make sure you get only the products you need. We work with you from taking off the plans to ordering to delivery. And there is service after the sale. You can call anytime to tap our reservoir of knowledge. When our customers are successful, we are successful.
