Merchant cargo buying and selling homebrew rules for The Expanse RPG

This is a set of quick rules for the buying and selling of merchant cargo in The Expanse RPG. I wrote it before I got Ships of the Expanse module, which has less abstract rules for that. We indeed switched to SotE's rules but here is the homebrew I wrote in case someone might find it usefull.

Feedback is much appreciated.
