Supply & Demand is the debut album by Atlanta duo Playaz Circle. The title of the album was believed to have been changed to "Pound 4 Pound", but in an interview Tity Boi confirmed the title to be "Supply & Demand". Playaz Circle released a single on called "Circle of Playaz", which featured Jazze Pha and then released "U Can Believe It" featuring Ludacris. The album was pushed back several times, but many tracks leaked onto the internet before release. The album was finally released on October 30, 2007, featuring guest spots by Ludacris, Shawnna, Phonte of Little Brother and Lil Wayne. The album was removed from iTunes in 2012, and it does not appear on music services such as Spotify and Google Play, most likely due to a copyright claim on the name of the group.

The album debuted at #27 on the Billboard 200, selling 26,138 copies. In its second week, it dropped to #79, selling 11,261 copies.
