Purchase Volume (PV) is our way of incentivizing members to purchase products from our store, and refer new members to our site. The Purchase Volume is calculated by dividing our portion of a revenue share agreement that we have worked out with the individual or company that owns the rights to an individual product in half. For instance, if we have a 60/40 revenue share agreement with a financial newsletter publisher that charges $100 per-month for subscriptions, the PV on this product would be $30—or 50% of our 60%. That $30 will be distributed among a member and their referral tree each time a member, or someone in their referral tree purchases a product from our store.
