I've designed this to be a very lightweight mod. It uses a series of carefully conditioned perks to accomplish nearly all of it's changes. The only script included in the mod is the MCM script that controls the menu options, so the mod will not cause any performance hit or save game bloat, and can be uninstalled cleanly at any time. To uninstall, go to the Mod Configuration Menu and click "Stop Mod." Once the mod is deactivated, simply delete the mod from your data folder.
In a small economy where individuals specialize in trades, they may find the process of setting up a centralized currency and maintaining it an unnecessary burden in order to trade. One option may be to use a commodity to exchange value between parties that want to trade goods or services and this is why gold and silver have been useful forms of currency in many cultures and times. Another option may be to use a barter system to trade.
Michael Linton originated the term "local exchange trading system" (LETS) in 1983 and for a time ran the Comox Valley LETSystems in Courtenay, British Columbia. LETS networks use interest-free local credit so direct swaps do not need to be made. For instance, a member may earn credit by doing childcare for one person and spend it later on carpentry with another person in the same network. In LETS, unlike other local currencies, no scrip is issued, but rather transactions are recorded in a central location open to all members. As credit is issued by the network members, for the benefit of the members themselves, LETS are considered mutual credit systems.
As Orlove noted, barter may occur in commercial economies, usually during periods of monetary crisis. During such a crisis, currency may be in short supply, or highly devalued through hyperinflation. In such cases, money ceases to be the universal medium of exchange or standard of value. Money may be in such short supply that it becomes an item of barter itself rather than the means of exchange. Barter may also occur when people cannot afford to keep money (as when hyperinflation quickly devalues it).
INDEPENDENT ADJUSTMENT - One issue with adjusting the barter values is that these settings change both the Buy and Sell prices. This can make it difficult to find a nice balance if you're trying to lower your selling prices without making the buying prices ridiculously high. Personally, I really like the challenge created by being forced to sell my gear at greatly reduced rates, but I dislike the extreme inflation that occurs when I then want to buy something. Therefore, the Independent Adjustments will allow you to increase or decrease the buying & selling prices independently of one another. This is something I've not seen in any other mod, and in my opinion, it's one of the best, and most useful, features included in this mod.
With 8.5 million members and 5,000 groups, Freecycle is like the mother of all garage sales, with one exception: Everything is free! The site started as a grassroots organization, encouraging members to reuse products rather than send them out to the landfills. For example, I have used Freecycle many times to find new owners for pieces of my cassette and record collection, piles of magazines and books, and assorted unneeded tools.
