snuggie domain

[wsamaan]

I recently purchased a domain called snuggieforkids.com. the company that makes the snuggie which is a blanket wants to buy the domain from me. they did not register their trademark till i purchased the domain. The kids product is called snugglette but they want to change the name to snuggie for kids. They are offering me $1000 but i told them $5000. I have sold their product thru this site as an affiliate but I am not sure if i could possibly monetize the site and make more down the road. The adult version of the product has sold $60 million. Wanted to get someones opinion with experience as i am new to this.
