Silverstreak was the last of the red boxed TRU reissues to go on clearance. Actually, I don't think he ever did. That figure kept slipping though the system because it wasn't marked as a "commemorative" figure in the system.

Anyways, $30 was the MSRP ... due to Prowl and Smokescreen being more popular because of the detailed paint apps ... I can't imagine the price flexing + or - $5 from that point.
