ALTHOUGH, the carrier only keeps a record if an investigation is filed by Amazon. Therefore if the price of the item is not that expensive they will give a refund right of the bat without filing an investigation, in that instance the carrier won't receive any notice of the shipping claim. You can do a lot of them, just not a lot at the same time. I've had about one USPS Claim, Four UPS Claims, and one FedEX Claim at my old address over the past three years. I'm assuming they use your name as part of the record along with your address.
There are way's around everything.
