How to Use A Contract

  1. Visit the Contracts webpage to view the contracts available to MiDEAL Members.
  2. Make direct contact with the designated vendor to make a purchase.
  3. If you don't find the contract you need, contact us to see if we can help.

Important notes on using contracts:

  • The State has not determined or can guarantee that MiDEAL contracts will meet local purchasing ordinances or policies.
  • The following actions are a violation of the MiDEAL Extended Purchasing Program and are grounds for removal from the program: 
    • Purchases made for personal use or consumption by any individual public employee.
    • Purchasing from MiDEAL contracts with the sole intent to resell the item.

    The contracts appearing on this site are available to MiDEAL members.  The MiDEAL Contract List link  is a searchable alphabetical list of all contracts available through the program; the list also includes a link to each contract.  Each contract includes a "bookmark" taking the viewer directly to the pricing pages of the contract.  Contracts on this list are competitively bid.
