I'm sorry to be such a pest about this, but I feel that I'm so close to having the right configuration.
For a few of my test orders this actually worked, but when I changed the address to any other address than the test address the system went to offering either the UPS only vs static USPS price for the entire cart.
The example is the UPS plug in works great at calculating the shipping costs for a seat to ship across country, an average of 14.00 USD. A pillow to go with the seat can ship from the USPS for 4.00 USD, and we obviously ship those from a different location.
When this worked properly the cart had some error messages (mostly due to the pillow having a weight in the shop of 900 lbs) but as you described the rate shown was 18.00. The 14 dollars plus the 4 dollars, and I'm certain an invoice on my end would have been easy enough to display what was ordered and where I'd need to place the shipment out to.
But now after switching the address for the test order the shipping methods show up either all UPS, and tries to ship the pillow for 12.00 (despite the 900 lbs..) plus the 14.00 USD. OR Manual method for 4.00 for the entire order.
Is there a step in the process I'm over looking?
I also have to say debugging this if I add a minimum order weight the manual shipping method doesn't show up what so ever. That's setting it at 151 lbs or 500 lbs, just so the pillow's fake weight would be noticed by the system.
Might there be some documentation on a successful set up of this somewhere on the board? Or any idea what I can add to fix it?
Really appreciate the help.
