There is commerce on Cybertron. For a great deal of time before Megatron reappeared, the post Great War has been a time where the Autobots have created many ways to entertain themselves. There are refuelery restaurants, energon bars, shopping arcades with every upgrade you could ever think of, as well as various forms of theater, music, and other entertainment.

There is a commerce guild that is in charge of the credit and energon banks.The head of this guild is Decimus Quadrillon, who is the richest mech on Cybertron. Rumor has it that Decimus' cube shaped headquarters is actually a giant bin containing over 30,000 square standard Cybertronian units of raw energon. There are even some wild and unlikely rumors that he dives into and swims through the energon. An act which would be very damaging on a Cybertronian's inner workings.

The Autobots have a distrust of other alien races (organics and non-organics), and do not engage in much, if any, off world trade in modern times. Cybertron has been invaded, conquered, and nearly conquered at different points throughout its vast history, leaving the Autobots with little care to act with outside civilizations.
