With the upcoming changes with postage services, I really wish that these postage channels would tell you off the bat what USPS zone the order is going to. Either that or USPS should overlap their zone boundaries with state boundaries to make it easier to compare zone sensitive services. I'm in west coast and Texas is split in half between zones 5 and 6, which can be a 4-5 dollar difference in postage.
Seeing the zones upfront would be a huge benefit.
