Kao disks (1993)

Come già detto in altri post, la corsa a vendere una scatola di dischetti si faceva anche regalandone uno in più, magari con un gioco, una demo o un concorso.

Il testo dice:

three more reasons to try the
world's favourite 3.5"disks.
free extra disk +free microsoft
windows for workgroups 3.1 demo
+ win a trip to seattle USA.
