Quoted from jhanley:I called USPS and they said a invoice was created but they never received anything.On Amazon in my orders it says it was shipped but there is no acceptance by USPS.
This has happened to me. Warehouse entanglement, not USPS fault. Call the company you ordered from and cancel the order and open a new order. That way you do not have to be involved in finding the lost one, it's not worth the effort. If you cannot deal direct with a company to cancel and reorder when using Amazon, that's a reason to not use Amazon.
