We actually did exactly this once, and our ref let us get away with it.
Essentially while NOT assaulting the guarded asteroid compound we had contracted to do, we grabbed the starship, combined our mustering out monies, and bought several tons of high TL solar powered scientific calculators (represented as Electronics I think), and proceeded to make huge bank selling them to a several wholesalers on a TL5 world, who were quite taken with them.
We made literally millions of Cr, and never laid foot on the guarded asteroid complex we were to assault.
Ref was kinda upset, but, frankly, he could have curtailed us at several junctures -- but didn't.
