I made my own very simple shipping based on total price (up to $5 = $3, $5.01-$10 = $5.20, $10.01 - $30 = 10.95, $30.01 -$50 = $14.95, $50.01 and up = $20) . The values the cart gives me are all over the place. A $5 item has shipping of $20 when it is supposed to be $3.00. If I add another item to the cart the shipping shows $14.95. I also tried using a weight scale and still got crazy results. What is going on? www.scentsationalbuys.com
