I just got my Tron Legacy Blu-ray. I got the fancy one that includes the free Light Cycle. The CUSA Ad is not separate but is part of six Ads on a small included fold out leaflet.
Included Ads on be foldout are Tron Uprising, Phinears and Ferr, Disney Vacation Planning DVD offer, Sylvania LED lightbulbs for the home, ESET Smart Security Antispyware software and yes CUSA C64.
I will scan the leaflet and upload it to Amiga.org later tonight for all to see.
