About Us

 Dear customer, for 29 years Great Lakes Auto Dealer Supply was dedicated to bringing you the best quality merchandise with the lowest possible prices. Even though our name has changed two years ago. It will still be our goal at Performance Supply and Marketing to continue that trend.

     Still to this day some of our products have not had a price increase since we started Great Lakes 29 years ago. In fact we have lowered prices on many items just for this web site. It will always be our goal to keep our prices as low as possible to save you, our customer as much money as possible. Especially in these trying times.

     At Performance Supply you will never see inflated shipping costs. In many cases shipping is free or at the absolute minimum. At Performance we will never be undersold. If you see any advertised price lower then P.S.M. We will gladly match and beat that price for exact items.    

     At Performance Supply we strive to carry quality merchandise from quality suppliers from the U.S.A. Some of these great suppliers are Versa Tags Inc, E-Z Lettering Service, Flag Source Inc, National Banner Co., Quality Banner Co., Deluxe Frame Co., and Anchor Line Products. Just to name a few. All from the U.S.A.

     Our mission is simple: to provide the best products and service to our customers at the lowest prices possible. We take great pride in our company, our commitment to customer service and in the products we sell. Our online store is designed to provide you with a safe and secure environment to browse and purchase our product.

     Call or shop Performance Supply today for the best quality, price and friendly service. We look forward to hearing from you soon.

Thank you,
