J&M Warehouse is a locally owned and operated network, security, and audio cabling equipment retail store. Our roots go back 50 years ago when J&M Warehouse (then named J&M Supply) was founded by Dickie Marshburn, a local who prided himself on providing quality products for an unbeatable price. These values still hold true today though our product line has differed by some degree over the past 50 years. We strive to provide this region of South Carolina with products that cannot be found anywhere else within a 100 mile radius, whether these items are ‘obsolete’, or simply not addressed in other business’ product line. Visit or call us today and let us help you prepare for your next project.
