Hi all! I've received a $250 offer via a broker from DomainAgents.com for one of my domains, Callisto dot co. The domain recently expired, but I managed to renew it in time I've checked Angel.co, and there are dozens of early-stage startups with that name. I've found more than a dozen company when I search callisto*.co* on Google. I've just noticed that I received a DomainAgents.com link to a negotiation page. It turns out that their original offer was $200, and $250 is already a counter offer. What do you think, how should I respond? I have a feeling that they just want to test the waters with this $250 offer.
