Business pricing is based on volume. We charge actual UPS and it isn't much of a discount off of list or non business. Without volume, you can't generate any meaningful discounts. Plus, you pay for pick up.All of the prices on that shipping list are actual shipping costs and not business pricing. When you have a UPS business account it cuts the shipping costs way down. I could run the actual numbers for you, but I can bet it costs them less than $10 to ship that part via UPS. I’ve shipped a 30lbs RC Crawler for less than $20 from Va to Oklahoma. So I guess there is a chance they’re pocketing extra money from shipping?
