So they paid about 4k each and sold them for $8 and change. Nice racket for some connected donor I bet.
It is a racket, for sure, and not a new one. These will be warehoused, and when needed again sold back to the government at full list. When I was a contract administrator (private sector) I remember seeing a clause in the F.A.R. requiring a vendor to certify that goods offered had not previously been sold as surplus. That was over 40 years ago. The game was old even then.
