Abstract: The present invention relates to and describes a method and system for Internet shoppers to purchase products at discounted prices using a members only scaled bidding process within an online shopping club. Internet shoppers would become members of a shopping club described in the present invention paying for the membership right and being granted with their membership a number of bids to be used within the shopping club before their membership expires. The shopping club would than use the membership fee to purchase items to be later bid upon by the members using a sliding scaled bidding process described in detail herein. By allowing members to now bid on items that the club has purchased, items are in essence already paid for by the members and not the shopping club, so members may bid ridiculously low dollar amounts in order to be the winning bid and win the right to purchase an item with no fear of bidding to high for the member is not obligated to purchase the item after they are the winning bid. Members with losing bids may still be afforded the option of purchasing the item at the winning bid amount if certain conditions are met.

Abstract: A water treatment system including a reverse osmosis module and a control valve controlling communication between a water source and the module. A feedwater biased storage tank stores permeate and its pressurization by feedwater is controlled by a feedwater control valve. Flow of signal pressure to a signal pressure chamber of the feedwater control valve is restricted to reduce the rate at which a fluid generated force is applied. A check valve in parallel with the restriction allows relatively unrestricted flow out of the signal chamber when signal pressure is terminated. A tank pressurization control valve controls the operation of the feedwater control valve and controls the pressurization of a feedwater biasing chamber in the storage tank. Per-meate is stored in an accumulator for flushing the reverse osmosis module when the storage tank reaches a predetermined limit. Cleaning substances or additives can be introduced into the system
