Hell Divers 2 Trolley Tokens

Going shopping for your family on Super Earth (or any other freedom approved colony) and don't have a coin to liberate a trolley? Just pull out one of these sample turn in credits (because actual samples are property of Super Earth and must be turned in to your designated S.E.A.F officer, they also don't fit in trolley slots) and liberate that trolley. Don't forget to return the trolley to its storage area when done, soldier!
