Usually if you do a regular RMA, I believe you have to send your unit in and wait for a return unit to come in the main. Cross shipping would be that you keep the unit and wait for another unit to come in, then once you get it, and if all works out, you send the bad unit in. If they said something difference, we'll need to find out. Ok, I'll ask and see what the deal is. If I can help save you as a customer, will this work for you? I can't guarantee anything however I'll see what I can do.
