While the original idea for Rehash was to design clothing out of recycled clothes, it eventually evolved into a site for trading clothes with other users. Members can trade their unwanted stuff (clothing and accessories) with others who are looking for new items for their wardrobe, and vice-versa. Rehash also acts as a social community where users can get green living advice, read articles, request items, and attend swap events. Membership is free to interested parties. 

The barter system is a type of trade that involves the exchange of goods and services without the use of money as a medium of exchange. Trade, on the other hand, is a broader concept that includes not just the barter system, but also, international trade, commodities trading, currency trading, etc. The main difference between barter and trade is that while barter trade does not involve money, other forms of trade occur with currency used as a medium of exchange. An important point to note is that the invention of trade whether barter or otherwise has developed a useful system under which individuals, businesses and nations can exchange or sell off the products or goods held in excess and purchase or obtain desired products, goods and services. The invention of currency has greatly simplified this process making trade convenient and fair.

I have made every attempt to keep this mod as compatible as possible with all other mods, and it should be fully compatible with nearly every mod out there. There are a few features that may conflict, but these can be toggled off to maintain compatibility. The features will work just fine with merchants added by other mods (assuming they've been placed in the proper factions). In fact, while this mod does work very well on it's own, my primary intention was to create a mod that would compliment and enhance existing mods that already overhaul Skyrim's economy.
In recent years, barter has enjoyed a resurgence as a means of countering economic insecurity, unemployment and worker exploitation. The nature of modern-day work, the pervasiveness of the Internet and the rise of social networking have all contributed to its spread. Other examples of alternative economic systems include gift economies, sharing economies and time banks.
Barter is a system of trade in which one party exchanges products, goods and services in order to obtain required products, goods and services possessed by another. In a barter system, no money exchanges hands between the buyer and the seller. Instead, both parties to the sale determine how much of a product a fair trade for another product or service. Since people assign different worth to different products, a barter system makes it difficult to decide how much of an item needs to be offered for another for the transaction to become a fair trade. Barter system was largely used long ago before the world developed the concept of currency for the exchange of goods. Nevertheless, the barter system is still prevalent today among nations, corporations, companies, individuals and businesses. The barter system makes trade easier for countries that experience large volatility in currency conversion and for countries that do not have sufficient financial resources, but have large volumes of commodities that can be traded for other commodities.
For instance, let's say your pipes burst at your home and you find yourself in need of a plumber. It's an emergency situation and if you don't hire a plumber fast, you'll be displaced and will have to move your family out of the house and into a temporary living situation. That certainly would be a bad thing. But should you barter your dog grooming services right now? Do you really want to trust your plumbing to the only person in town who'll do the job if you shampoo their poodle?
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.
Economic historian Karl Polanyi has argued that where barter is widespread, and cash supplies limited, barter is aided by the use of credit, brokerage, and money as a unit of account (i.e. used to price items). All of these strategies are found in ancient economies including Ptolemaic Egypt. They are also the basis for more recent barter exchange systems.[17]

In his analysis of barter between coastal and inland villages in the Trobriand Islands, Keith Hart highlighted the difference between highly ceremonial gift exchange between community leaders, and the barter that occurs between individual households. The haggling that takes place between strangers is possible because of the larger temporary political order established by the gift exchanges of leaders. From this he concludes that barter is "an atomized interaction predicated upon the presence of society" (i.e. that social order established by gift exchange), and not typical between complete strangers.[13]
