Sending a large 10 box, 1,800 plus unit shipment to FBA, but using the 5 location option are all of my FBA shipments are going to the West Coast exclusively. I split up the items so 5 locations could get the same skus and nearly identical quantities but not one of my 10 boxes is going to an East Coast location. If the point of having us split it up is to expedite the transfer of FBA inventory, why am I not shipping at least some to the East Coast and Mid West?

There is no way these Skus aren't selling to East Coast buyers. As is this shipment will take 7 days to get from me in NY to CA, then FBA has to transfer them back to NY to fill orders? Makes absolutely no sense. Seller Support tells me there are no restrictions associated to allocation and the shipment I created has no issues or errors. SS tells me "How inventory placement works is, the shipment is first shipped to the main warehouse where the shipment is divided and then sent to other centers" So does that mean there are no "Main" warehouses anywhere but in CA?

I took the time to sort and pack 10 nearly identical boxes with 40+ different skus figuring common sense would dictate they'd be split up into different regions. I could choose to ship using the 3 location option with inventory placement fees starting at X. How accurate is that "starting" figure? Will I expect to pay X, only to be charged 2X, 5X, or 10X?

Any assistance would be greatly appreciated, expect to make another large shipment tomorrow but hoping for better options. Thanks.
