I know this is an older thread, but yes, I do believe the domain name has a big impact on the SEO for that website. If you can get both domain names as the others have said, the better. However, there are limited versions of "ofthemonth" type domains these days. Adding "club" to a subscription company has similar effects.
For example, the company I work for is Gold Medal Wine Club. Years and years ago we changed our URL to include "club" and it has so far been a smart move!
