Wal-Mart has claimed that Garth Brooks’ new limited-edition box set has sold more than 1 million units, as of Wednesday (Dec. 7). The set, retailing for $25, went on sale Nov. 23 only at Wal-Mart. Since sales figures are not being supplied to Nielsen SoundScan, the sales totals are impossible to confirm. Since it is a single-outlet exclusive item and is not being reported to SoundScan, Billboard is not including the set on its sales charts. It includes four previously released CDs, a “lost sessions” CD with 11 new tracks and a commemorative DVD. It also has “Good Ride Cowboy,” now sitting at No. 4 on the Billboard Hot Country Singles and Tracks chart, which reflects radio play.
