"Thank you for contacting Pool.com customer service.
I did submit your offer to our client but they've declined.
They confirmed they do have plans to develop a site using this name and for that reason they have it valued at a higher amount. They did not provide any counter offer. "

Your offer was FAR to low.
It's a 3 letter domain which makes sense.
