You still have to check SAM.gov
Department of Veterans Affairs put out a solicitation on SAM.gov for "surgical instrument maintenance and repair". Incumbent never saw the solicitation and, obviously, never proposed. GAO said that posting on SAM.gov was all that was needed. Incumbent also claimed that VA was required to keep doing purchase-card transactions under a previously cancelled solicitations. The VA and GAO disagreed. Also, the protestor used a lot of AI and got citations wrong and GAO was unamused.
