To calculate your commission simply subtract the cost of the meds you sell from the sale price, you keep 60% we keep 40%. If you set the shipping charge to more than, or less than, the normal $23.95 shipping charge (next day), or if you have Affiliates, or are using coupons, the commission formula is more complicated. The commission formula is (SALE_PRICE + SHIPPING_CHARGE – COST_OF_MEDS – COST_OF_SHIPPING) * 60%. The COST_OF_SHIPPING is our fixed $23.95 charge (next day). Payouts (if any) to your Affiliates are subtracted from the order profit before commission is calculated.
