The funny thing they could do is advertising for real life companies like Coke or Taco Bell.
And replace some of the trade items with items linked to these companies for a limited time.
"New new Coke" and "Taco "meat" filling" (imperial slaves) are some of the thing that could be traded...
Add in some real life link... bring 100T of "meat" and receive 10% reduction on your next taco bell purchase (but who would take that offer though, seriously?!)
This in turn would raise the demand for Pepto Bismol at the station because of the "meat" quality.
Because no matter how they are fed, space weevil is not good taco material.
