The fourth and final installment of The Twilight Saga, Breaking Dawn--Part 1 is on pace to outsell the previous movie's DVDs and Blu-Ray discs, selling 3.2 million units in the weekend leading up to Valentine's Day.

Sales are 18 percent more than those of the third Twilight movie, Eclipse, which sold 2.7 million units its first weekend of release, according to the Chicago Tribune.

Despite the huge sales, Breaking Dawn--Part 1 remains behind the debut sales of New Moon, the second Twilight movie, which sold 4 million copies in its first week, reports the Los Angeles Times.

The first movie in the saga, Twilight, sold 3.8 million copies in its first weekend.

Discs for Breaking Dawn--Part 1 went on sale at midnight on Saturday, timing that's typically reserved for titles with a massive following. Large retailers such as Target and Wal-Mart sold exclusive versions of Breaking Dawn--Part 1 DVDs and Blu-rays. These stores also held special events for those waiting for the release.

Summit, the production company that made the series, told the Chicago Tribune it had sold approximately 50,000 digital sales, a 47 percent increase over Eclipse. The Los Angeles Times notes that the wholesale price of Breaking Dawn is more than the Twilight movies have been previously, meaning that the net revenue is likely higher.
