Note: This procedure involves editing a game file; create a backup copy of the file before proceeding. Start a game, dock at a space station, and buy some cheap commodities (for example, iron). Undock, save the game, and quit. Locate the file in the game's folder with the "BuyValue" line. Edit the "BuyValue" line to a desired price, then save the file. Start the game, and load the previous saved game file. Dock at a space station, and sell the commodities that were bought earlier. The sales price will be at your edited price, allowing you to make a large amount of money in one transaction.Free Destroyer Class ship and credits
