>Sorters
USGspending.gov has lots of contracts under the search term "sorter"…. Just two examples capped. These are listed by transaction and don't necessarily reflect the totatality of the contract. See Proquest for example. The transaction amt. is far less than the $32M paid to them over the life of the contract. If you have a specific vendor name, go to 'profiles' tab, then to 'recipient', type in the name and a history of their USG transactions will show up.
