Now we’ll say another 1/4 live quite a distance from GPF pickup branches but are in range of GPF’s Home Delivery Service, delivered directly from warehouses = another $4,550,000 in retail value.
 

Let’s then say the Home Delivery Service cuts shipping costs by 50%, compelling GPF members to raise winning bids and BUYs to a total of 85% of retail = $3,867,500….minus $2,500,000 gives the GPF a gain of $1,367,500.

Meanwhile, our Warehousing friends earn $200,000 = 50,000 X ($2 + $2).
