It is really a shame that most people's experience of NJ is only the Turnpike and the refineries around EWR.
When I lived in New Jersey, the gas stations in New York would offer spiffs with a fill-up, and there was always a disclaimer "offer not valid in New Jersey," which made it seem like the spiff wasn't available at all in New Jersey. For those who knew, the rule was actually that gas companies couldn't require a minimum purchase to get the spiff in New Jersey, so if you knew what you were doing, you could put a gallon in and still get whatever the free item was.
But I haven't lived in New Jersey since gas was priced in ¢, and not $.
Think of the big bags of crap that used to be given away at CES, or when a Microsoft rep would show up in the office and hand everyone new mouse pads.
