A massive effort is underway to get 1.5m copies of the Band Aid 20 single in the shops by Thursday.
NR's Ellie at the warehouse
Newsround's Ellie went to the warehouse in Milton Keynes where staff are working hard to make the deadline.
The CDs will be around £4, but costs have been kept down to make sure most of the cash helps people in Sudan.
More than 500,000 copies are already ready to go. The CD will hit the shops less than two weeks after a galaxy of stars sang together to make the track.
The CDs are being delivered
It features artists including Robbie Williams, Will Young, Sugababes and Jamelia.
It will be available to buy from Monday and looks set to go straight to number one the following Sunday.
The song - Do They Know It's Christmas? - was originally recorded 20 years ago, when it raised money for starving people in Africa.
