If your band has a number of gigs lined up over the next month or two, you can order a large batch of CDs so that you’ll have enough on hand to sell after your performances. But what if you only have a performance scheduled for this week, after which you might want to change the track list or re-order the songs on your CD? If you’ve commissioned a large order of CDs, you’ll either have to sell all of them or discard them before you make those changes.
