We have a good bartering system out here. All of our services and goods are avaialble via this system. You earn or bring your own credits for the system and use these to gain the products or services you require. The credits are often printed on paper or are made from metal discs. If you work for your credits ask how many you will receive in return for the amount of work. Look after your credits. We have special places that will look after these credits and give you other bits of paper or peices of plastc to use as credits instead of the disks and paer. These alternate peices of plastic and paper cost a few extra discs to use and are still widely accepted having the benfit of being supposedly safer than the intial discs and paper.
Lastly. More is more.
