On Time Digital REFUSED to give me their mailing address!!! New York City New York

When I Googled for the camera I was looking for (Nikon P80 Digital Camera), Ontimedigital came up offering it for $179 including S/H. That price is half of what a well known local retailer is offering. So I called ontimedigital and was on various on-hold messages until a fellow with a very strong Nu Yuawk accent came on. He sounded like he was doing me a big favor by answering my call.

When I asked him, "just out of curiosity, how can you guys sell the camera for half of what other retailers are selling? He said nothing. So after a while I said, "hello, are you there?" He finally said, "I don't know. I'll switch you" When another rather impatient person came on line, I asked, "May I have your mailing address, please?" Another long pause later, he said, "We can't disclose that information for security reasons" So I said, "Fine, I am not buying from you, for security reasons"

What would that security reason be? A retailer that won't tell you their physical address? What are they hiding?
