Could it have something to do with right to return under State law? (Guy doesn't like his (whatever purchase) here in MN within 3 days. Its easier to return that item to the local FFL under the States (3-day right to return) Purchase Law than it is to send it back to its original owner across State borders hopping to get a timely refund. Once a FFL holder is involved and a fee has been paid for the transaction. The FFL holder is expected to pursue the refund in behalf of his client.)
