The "replicas" are NOT cheaper made at all. They were made by the same company,
CPC, and are of the same high quality. Only the label was modified to distinguish the replicas from those used in the movie. Same mold, same colors, just a slightly modified label.
Here is the thread where it was discussed with
@David Spragg how to modify the original label.
