I see nothing wrong with using a USPS flat rate envelope to ship a box that isn't a new, unused USPS flat rate box. In that scenario, "if it fits, it ships" is correct usage of the envelope.I don't do this persay - but I do use a box roughly the same size as the priority small flat rate box, and put that inside the flat rate envelope. It gives the items more protection from the USPS just throwing the boxes around, so there is less damage and less chance of having to replace/refund items.
Even though I know people find this unethical or wrong or whatever, I personally do not see any harm in this practice.
