PURCHASE Purchase is the method used forgetting material or services  not  available  in  the  supply  system.  The NAVSUPINST  4200.85  provides  instructions  and guidance   concerning   purchase   or   procurement   of material from commercial suppliers. Small purchase means an acquisition of supplies and  nonpersonal  services  for  $25,000  or  less.  The process for open market requirements of more than $25,000  is  through  formal  contracting  procedures. Chapter  1,  enclosure  2,  of  NAVSUPINST  4200.85 describes the procedures used for small purchases. The preferred  sources  of  supply  are  government  activities. You can use open market purchases only when required items are not available from mandatory government sources of supplies. These sources are as follows: Department  of  Defense/Federal  Supply  System for  material  with  NSN Excess personal property from other agencies Federal  Prison  Industries 4-9
