I definitely know now. ThanksBeing on an approved list simply means that they have established a relationship with Brownells and Brownells does not have to call and check that they are legitimate FFL.
I think that people are trying to "nudge" you into being a courteous customer and letting the FFL know that something is inbound for you.
Simple common courtesy goes a long ways. On both sides of the transaction.
