sounds like a regional thing. when i purchased 20 boxes of .223 tula last week they were out on the shelf and i put them in my little basket and carried them up to the register. did not have to show ID and the only thing the girl at the register asked for was if i had their reward club card.
They used to be very anti EBR but recently have opened up and started carrying brands like troy and viking tactics.
I used all of my available credits at Dick's, mostly for premium .223 and .308 ammo. Didn't have to sign any lists or have my D.L. number recorded, as recently as ten months ago or so. I was disappointed when the recycling system was changed - I had a good thing going. I was even hauling home the heavy cardboard from my office warehouse to pump up my points. :-)
