(a) It is preferable to have multiple BPAs for similar items and to establish prices using reverse auctions among BPA holders. If quantities are too small and not conducive to using a reverse auction, then when practicable, contracting officers should establish pre-priced BPAs by negotiating firm unit prices for specific periods of time or by incorporating suppliers’ price lists or catalogs in BPAs.

(b) Contracting officers should not establish blanket purchase agreements for supplies or services when the use of unpriced purchase orders is appropriate (see FAR 13.302-2).
