Wish it was a local shop, transfer fees make this a bit untenable.

Heck of a deal.
Should only be 1 transfer fee since they all go on same form.

That's going to depend on the individual dealer's policy, every FFL does it differently.

"One transfer fee per box of guns"
"One transfer fee per each firearm"
"One transfer fee for up to 3 firearms"
"One transfer fee for each handgun/ one transfer fee for 1-5 long guns or receivers"

Etc ............
