Hi I don't know what department chains you have in New Jersey, but some of the bigger ones carry the liquid splenda. Actually have you checked the dollars stores or some of that nature, sometimes they carry some of the most hard to find things also.
Good Luck

Couldn't you even liquify the gradular spenda?
A good question, anyone else know if you could do this and get the same measurements as you would need with the liquid splenda?
