I'm from NJ also and have to take a drug screen for work soon. I ran into the same issue with sites not shipping to NJ. I bought quick fix plus on ebay, but the listing was cancelled by ebay shortly after I paid. I'm not sure exactly what is happening with that bottle. I ordered a bottle of quick fix plus (3oz) from keepshooting.com, but they called and said it was out of stock (maybe getting more on 8/6). After talking to their customer service, I had the order changed to the regular quick fix (2oz) and according to the tracking number they gave me, it has been shipped and should arrive tomorrow. I'm also supposed to be getting some clean piss from a friend.

Never had to take a drug screen before, so I don't have any insight about the difference between the two products. The only time I was at a Bio-reference lab was to get some blood work done. The one I was at was just a small two room (reception area and lab area) place in an office building with one person working there.
