If you are I purchased online or at the store.
Federal government would require a study at a cost of tens of thousands and purchase 100 units. This is how we get pay $600 for a hammer.
Here in California, they would have a group of state employed engineers rewrite the specifications so that no off the shelf part would meet. Some manufacturer would retool, but for a minimum order of 10,000 units. The state only needs 5 so they would procure the 10,000 units at a cost of $400 each. Then they would sell the 9,995 units for $20 at auction to raise cash because the state is broke.
