Where Can I Buy Coffee Crisp Bars in Either Washington, DC or Northern New Jersey?

I'm looking for Nestle's Coffee Crisp bars, if anyone knows a store that sells them. They're Canadian, and aren't generally sold in the US. I'm going to college in DC, but I'm graduating in less than two weeks. I live in northern New Jersey, so if anyone knows of a store in that area (NYC would work as well), that'd be extremely helpful. Thanks! =)
