Question on running nitrogen

yeah thats how they do it. every time you go to get a new bottle they give you a new one. just umplug your regulator and give em the bottle. some will ask you to buy the bottle from them so they can do it, something with the logo or manufacturer not too sure.

yea thats how most all of them are, but my bro works at Autozone down there and he gives them the hookup on parts since he is the parts manager. I guess this will be their way to repay him.
