If you wanted to make a trip into SJ, I know for a fact that they carry it at Hayward and Warwick (85 Princess St). I work there. Will for the next week, anyway! Going back to school.
The owner of Kiss My Face is actually the owner of Haywards' brother-in-law. They also carry toothpastes, bubble baths, face/hand creams.. all sorts of things. Anything they don't have in stock, they can always order in as well. But if you went the way from sussex, you'd want to make sure they had what you wanted, so I'd suggest calling first.
I'd imagine they'd ship it to you if you couldn't drive in, and you can pay with a credit card over the phone. You just have to ask, and they can quote you the charges.. but make sure you call on a weekday if you want to do that because the shipping guys don't work on weekends.
