Not 4 Sale is the fourth studio album by Canadian rapper Kardinal Offishall, released September 9, 2008 on Kon Live Distribution and Geffen Records.

It was a critical success, and included the top five Billboard Hot 100 single "Dangerous", and the minor hit "Numba 1 (Tide Is High)".

On July 2, 2007, the single "Graveyard Shift", featuring Akon, was premiered on Sirius Satellite Radio's Hip-Hop Nation channel.

Kardinal explained why he chose Not 4 Sale as the title: My idea was something provocative — that went beyond gender, went beyond race, went beyond what type of music you're into.

AllMusic gave it 4 out of 5 stars, calling it "an entirely solid album," also stating "this freedom fighting and socially conscious writing is tempered with hooky club tracks that never fail.

"[16] PopMatters gave the album a 6/10 rating, writing "although many of the tracks here are glossy pop productions, Kardinal has not really changed since he was first heard in the '90s.
