I'm not sure if you are looking to purchase tape on the web, or in person. If you're doing it online, I recommend toolsforstagecraft.com. I needed a rush order from them and they were very helpful and kind. I also have a soft-spot in my heart for smaller companies, so maybe that recommendation is slightly biased.
If you have access to getting into the city (I noticed one of your locations is Bergen County, not a far cry from NYC at all), you have a lot of options.
The theatrical lighting suppliers in town all carry expendables like spike / gaffers / glow tape. I've used Barbizon Lighting (55th St. at 10th Ave) , SLD Lighting (47th between 8th and 9th Ave) and Garden Hardware (10th Ave at 48th Street).
