Gun sales skyrocketing

So I've read that NICS checks are up 300%.    I picked up an internet purchase at a LGS.  First time using this particular shop, Doomsday Tactical.  He does $10 transfers.  Before using him I checked out his fb page and he said he's selling 35-75 guns per day.  I went in to pick up my new purchase, Stribog SP9A1 just after he opened yesterday at 10AM.  his shop was hammered busy.  Three guys behind the gun counter moving as fast as they could to get the 4473s.  Guys walking in asking for a"9" and then buying an AR too...  NICS was delaying alot of buyers, mine came back about 15 minutes slower than usual, I usually comeback with in a minute or two approved.   In the 45 minutes I was in his shop I bet they sold  10 guns.  Counter guy said they've been hammered like this for weeks, sometimes staying an hour and half past close each night.  He said they can't keep magazines or ammo, including shotgun ammo.     I typically use pawn shops for transfers, I've not had great experiences with most LGS.  But these guys were pretty cool for gun shop employees (they were actually friendly, approachable and laid back).  I'm definitely going to give them more business, I need to find something their shop to buy.
