NAVMEDCOMINST 5604.1. GSA periodically makes open-end contracts that cover the procurement of books. All books are procured under the provisions of these contracts.
Figure 14-6.Requisition and Invoice/Shipping Document, DD Form 1149 (multiple requests).
Purchase actions are normally taken by a shore activity as a result of ships requisitions. However, ships supply officers and commanding officers of ships without Supply Corps officers may obtain requirements for supplies or services by purchase on the open market.
Purchases afloat are made by one of the following methods:
1. Purchase order for purchases not in excess of ,000.
2. Imprest fund for cash purchases not in excess of 0.
3. Orders under indefinite delivery-type contracts and blanket purchase agreements (BPAs) that have been negotiated by shore activities.
A single requirement may NOT be divided with more than one purchase action for the purpose of avoiding monetary limitations.
Procedures for purchases by ashore activities are provided in NAVSUP P-467.
