Offers.com (at the time a record-breaking price paid for a domain name) is still getting peanuts in traffic compared to retailmenot, which has the dumbest name ever. And I'd argue offers.com has marginally superior content, except for the odd exclusive deal that retailmenot is able to swing based on their identity. But retailmenot got there first, and it hit the ground running building marketshare, and that has made all the difference.
