WISCO was organized in 1972 with the mission to save member dealers money through group purchases and to return any year-end earnings to the participating member. WISCO offers its dealer members the opportunity to purchase OEM parts, supplies, equipment, batteries, oil, and other miscellaneous items and programs at the lowest possible prices. With few exceptions WISCO offers its members anything a dealership can use except the vehicles.

Currently 534 auto and truck dealers with nearly 700 locations are members. Since its beginning, sales at wholesale prices have gone over 739 million dollars. In addition, patronage rebates based on member purchases have been over 20.6 million dollars. This is on top of the savings members received at the time of purchase. These facts demonstrate the effectiveness of the program in achieving its sole purpose -- to improve the dealer's "bottom line." Dealers using the program have realized profits that would not otherwise have been available to them.

The WISCO program is simple. There are no minimums to buy. Parts include AC-DELCO, Draw-Tite, Curt, FVP parts, Access tonneau covers, DualLiner bed liners, Weather Tech, and hundreds more. Equipment in the program includes Challenger, Hunter, Garmat, Global Finishing Systems, Espen Lighting, Altech Electronics exterior LED lighting, Borroughs, Equipto, Shure, Black Gold, OTC, Robinair, and other nationally known companies. Supplies such as 3M, Kimberly-Clark, GP and Tork paper products, Microflex Gloves, Wynn's, and Slip N Grip are included in the program. Antifreeze, refrigerant, Pennzoil-Quaker State motor oil, solvent recycling programs, and other items by equally well known companies are also available. WISCO has programs in place with MSC Industrial Supply Co, Wurth, Kent, Crest, and other hardware/supplies companies to save its members money. There is a national account program available for uniform rental and facility maintenance through G&K Services/Cintas. Cintas also offers a first aid and safety products national account program through WISCO. There is a spray on bed liner program through Rhino Pro. ECP/Auto Armor has a program available for rust prevention, paint and fabric protection, and detailing. Shipping time is generally one to two days via UPS/FEDEX/SPEE-DEE/WALTCO. Same day delivery is available on some items.

Members receive product specials and updates. WISCO provides toll-free phone calls with an experienced staff waiting to help with questions, pricing, and ordering. The WISCO web site is www.wisco.com. This site has a members' only section which includes specials and an ordering section.

The governing body of WISCO consists of dealers elected by the general membership to serve on the Board of Directors who in turn elect officers.
