Firearm transfer fee is $30 per firearm. So if you buy 10 AR-15 stripped lowers from Brownells and have them all transferred through Lock N Load, you will pay $300 in transfer fees. I just learned this the hard way.
Other than that, the staff is friendly and the selection is good. Most of the firearms they stock are quality so you don't have to worry about them trying to sell you something that's crap at too high a price just because the margins are better. They make their money like a respectable gun store: charging MSRP on ammo and tactical nylon gear. Which I can't hold against them, because they're charging reasonable prices on the guns and they have to keep the doors open somehow.
