Scanned my FFL03 into a PDF and emailed it to several companies.
Discounts in place from Brownell's, Midway, Numrich; FFL on file with AIM Surplus (they say they will have a discount program in place in March or so), J&G want me to mail a copy to them to go on file. Widener's replied they have no FFL discount program. All this from emails out Sunday about 4pm and responses by noon om Monday. The discounts range from about 10% for Numrich and Midway (10% or less on some items), to something more at Brownell's (does not look like an absolute percentage).
I think everyone I emailed responded.
