It's just 4 random letters correct?

I don't see you making any money on that at all. A great domain name is short, easy to remember, and highly relevant to something that you can monetize. Unless I'm missing something, you only have one of those and that alone is essentially worthless.

You're dealing with an extremely illiquid market. There are very, very few buyers in the world that would be interested in asow.com. You're best bet is to contact places that would abbreviate to ASOW (e.g. American School of Warsaw). I'd expect $500-$1000 if you're lucky. $200-$250 if you're not.

I have vflea.com.

Anybody know a good use for it?!

What about to represent some type of "Virtual Flea Market" or maybe a pest control or animal flea product website. Have you tried selling it anywhere?
