Under FAR 8.405-6(c) agencies are not required to go out to bid for every renewal of a existing contract. If the previous contract was competitively bid, in the interest of efficiency logical follow on contracts do not have to go through the same open competition process. See FAR 8.405-6 here.
The "no bid or price comparison" for micro purchases (under $3000) applies to GSA Schedule price list (FAR 804.4) You comply with the requirements of CICA (Competition in Contracting Act - FAR 6.102 (d) (3)) when ordering off the Federal Supply Schedule. GSA Schedules are to be the "Preferred Sources of Supply" for DOD (memorandum from Eleanor R. Spector, Director - Defense Procurement (OUSD), 3-6-97) Agency’s are justified in ordering higher priced items from the Federal Supply Schedule vs. Open Market. GAO has ruled that when placing FSS orders, an agencyneed not order lower priced items that do not meet its needs. The determination of the agency’s needs - and which product best meets them - is the Agency's responsibility. (CAPD Technologies, Inc., GSAP, B-278582.2, 2/19/98, released 2/24/98)
