I think you guys are giving NYC too much credit.
I live in CT, and was looking for a folding stock for a bolt action rifle...Cheaper Than Dirt's website wouldn't sell to me, i imagine because of confusion with the No-folding-stocks-on-semiautomatic-rifles state law.
I called them; a lady there said that's their policy. I asked for the manager, he said that too. I can't argue with that; but i can and did take my business elsewhere....and now they're loosing money on me, since they send me all those catalogs every other week that go straight into the recycle bin.
