A new internet trading method, concept and process is introduced, enabling users to post goods and services for sale and purchasing, whereby the posted price begins at its maximum, and thereafter is gradually reduced to a minimum, pre-selected price, based on pre-programmed methods and programs, according to a pre-selected schedule of price reduction based on frequencies and sequences of amounts of time, money and percentage, respectively.The new process provides sets of pre-programmed price reduction schedules which may be prepared by the seller, or selected from a pool of sets, or randomly selected from the system, thereby, at every certain amount of pre-selected times, the maximum price of such goods or services is reduced by certain amount of money, or percentage, respectively to the maximum price initially posted during the duration of the sale, enabling a prospective buyer to ‘grab’ (purchase) the item by placing an offer at any given time, for the posted price at that time, thereby instantly purchasing the product or service, thus also, instantly, ending the sale.
