Let's say that you want to make it more difficult to make a quick profit from the items you sell. So you decide to increase the barter settings to 10.0 and 6.5. At these settings, you will receive only 10-15% of an item's value (vanilla is 30-50%). However, you'll suddenly discover that the cost to purchase items has skyrocketed to 1000-650% (vanilla purchase costs are 330-200%). Maybe this is exactly what you want. If so, congrats, there's no need for you to mess with the Independent Adjustments. However, if you would like to reduce the purchase price to a more reasonable level, then you can use the Buying Prices adjustment to lower only the buying prices without affecting the selling prices.
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.
