Abstract: Internet discounted volume pricing with early participation discounting or “Jump-in Pricing” feature in which a person with quantities of a product/services to sell is prompted to enter in some price points on a website for a defined amount of time. As an individual or group of buyers buy/participate in a listing, the price of that product/service declines. The current price is the price that the seller will not pay more than (excluding shipping and taxes if applicable). The sell-out price is the lowest possible price a buyer or collection of buyers will pay (excluding shipping and taxes if applicable) if the entire quantity sells out. The seller offers “Jump-in Pricing” which is a discount to early participants/buyers of a listing to provide an incentive to a person or person(s) to get in early and start the pricing reduction.
