Love Solutions is a matchmaking service with a 100% track record.
Ellen Pierce, the woman in charge of the matchmaking service, states that she "can work with" a skeptical Ted and convinces him that she can truly help him find a soul mate in 3 days. He returns to Love Solutions, only to find that his chances for finding a soul mate are zero. The closest match compatible with Ted has already been matched up. Ted sneaks back in and finds out she is a dermatologist and makes an appointment to see her. He learns that she is engaged and will be getting married in a few days.
Later when Ted returns to Love Solutions, and finds that because he has no soul mate (according to the computer), the company is ruined, as the 100% success rate no longer exists. Ted, however, has hope that he will find his soul mate and says she can help as she is now doing it for free.
About 6 months later, in Milk, Ted gets a call from Love Solutions, saying that they have found him a match. He goes and finds a new guy in charge there called Bob Rorschach instead of Ellen Pierce, as the company has merely changed hands. Bob gives Ted a perfect girl's file who meets all of the standards on his checklist. This costs Ted $500.
