Rates are the same everywhere in the US, and are based upon distance => zone and weight. The reimbursement will pay for the required Scenario A and B service up to a total weight of 1 lb 15 ounces (technically 2 lbs and 0 ounces, but that is playing with fire) sent to Zones 1 through 4, inclusive (and you are required to ship a package weighing 1 lb 2 ounces or more). If you ship to a higher zone, then you are getting a discount. Scenario C requires shipping a package to Zone 5 or higher and the package has to meet the required minimum weight and weight less than 5 lbs because the intent is to trigger Dimensional Weight shipping surcharges. If you send more than 5 pounds, it will be an expensive lesson (I learned my lesson). Also, size matter. Stay below 13" in any dimension for Scenario A and B. For Scenario C, only 4 specific box sizes are permitted, and the key with them is that one dimension is 14 inches or more (it get a little more complicated than that, but you can always check on the USPS website). In my area, I am always required to ship to a specific food bank for Scenario C. Some shoppers have reported that in their areas, they are allowed to ship to anyone as long as the zone requirements are met.
