OK, we're getting close. The cart still doesn't seem to be calculating the shipping accurately. It's charging the same for 1 pound as 10 pounds. The shipping price doesn't actually change until the weight exceeds 12 pounds. The online store system my client is currently using (MIVA), is calculating the shipping exactly the same as when they go directly to the UPS site. Is it possible to get eCart to do the same? We'll be happy to pay you to make that happen.
