This domain was registered for a project that never got off the ground, but I still think it's a good idea: online marketing of travel and tours for singles. As Shakespeare wrote, "foot loose and fancy free" describes a person who is unattached, single, no strings, available, looking for romance and ready to travel.
There are many other possibilities for this domain name. If you are not in the travel business, how about a web site offering free samples of high end products to elite customers? But, we don't have to stop there. The phrase "fancy free" is embedded in our culture and it will surely be used in some future marketing campaign.
Here are some examples of how the phrase "fancy free" has been used. "No Strings (I'm Fancy Free)" was a popular song written by Irving Berlin for the 1935 film Top Hat, where it was introduced by Fred Astaire. In 1944, Leonard Bernstein and Jerome Robbins produced the hit musical
"Fancy Free". In 1947, Walt Disney produced the feature length cartoon
"Fun and Fancy Free" -- (come on, Disney, make me an offer). "Foot Loose & Fancy Free" was Rod Stewart's eighth album, released in 1977. The Oak Ridge Boys had an album in 1981 titled "Fancy Free".

While not (yet) on the popularity level of Fred Astaire or Rod Stewart, there is an electro punk group based in Mexico City with the unlikely name of
Los Fancy Free. The front man for this group, Martin Thulin, was born into a Swedish Mennonite community in Mexico, and the group's debut album was "Menonita Rock". (If you have been to Mexico City or Guadalajara and wondered about those blond Mexicans selling cheese on the streets, well, they are Swedish Mennonites whose ancestors settled in Mexico about a century ago. Of course, this trivia has nothing to do with selling a domain name, but I find it interesting.)
A Google search on the phrase
"fancy free" produces more than 700,000 hits.
Getting back to the original idea, if you buy FancyFree.com with the intention of using this name for a site focused on travel and tourism for singles, I would welcome an invitation to contribute to your business plan.
