I have been personally ripped off more than once by companies that "went out of business." The parentheses because, in many cases (like this one) the closure is not what people visualize, with chained doors, etc. There are still assets, employees, offices. In one case I was able to recover what was owed by calling the officers of the "old" company at their "new" jobs, every day, until I got my money. Did they legally owe it to me? Technically, probably not. I shamed/annoyed them into it.
I don't know 2600 from The Readers Digest, but I DO read several titles distributed by TEN: The Enthusiast Network; in one case I know the people at the magazine personally. I'll be writing letters and having conversations with these publishers about the people they're doing business with.
