What Sard is proposing would raise the value of a donation coupon, Berserk. . In a free economy where the majority of the economy is controlled by private investors ( players) an item in high demand ( which coupons are) will increase/decrease in price depending on its flow. When coupons are injected into the economy ( via events/donations) there are more coupons in the economy thus, since they are easier to obtain ( aka cheaper) and the demand for them continues to stay high, people can sell them for less and still strike a profit. An example in real life would be, the selling of wii's online; they are close to impossible to get thus people are getting away with selling them for twice their value, the demand for it is so great. In Conclusion, what sard wants to do is diminish the amount of coupons in the economy thus raising its value going by the theory that the demand for said item will online increase ( which, it will).
