Wondering what the difference is between duplication and replication?

CD duplication refers to the process of burning a CD-R, similar to the way one can burn CDs on a computer, but with a quality direct-to-disc print rather than a store-bought label that can get stuck in a CD player. (We've seen that happen, folks and it ain't pretty.) Duplication is ideal for quick turnaround times and smaller budgets.

CD replication refers to the manufacturing process that starts with raw materials to manufacture your discs from scratch. This is exactly how the the majors press up their CDs. CD replication offers a longer turnaround time, but better price-points.
