John Legend has pledged to donate a portion of the proceeds from his official merchandise to charity.
The Green Light singer has long called for an end to poverty in Africa and set up his Show Me Campaign for the cause in 2007.
He's now vowed to boost his fund by handing over $1 to the charity for every $20 wallet he sells on his official site.
A post on his Twitter.com page reads, "Happy Cyber Monday. For every wallet sold, $1 will go to showmecampaign All tees $10. Get 'em while they last!"
