So do I just mail out copies of the FFL, or is there a special address for each distributor to send it to?
Mail the copies, or FAX them if the distributor accepts them. tell them you want on their mailing list, and give them an email address for emailed fliers. Also send a copy to Midway, Graf & Sons, Brownells, etc because they will give you a dealer discount on their items as well.
Then get a bigger safe, and watch your bank account dwindle. Just part of the game!!!
