Noticed recently that most of the 4th gen GGs are releasing jewel case or light versions (some with member versions) which is priced extremely low. These versions basically explain why the sales of 4th gen GGs like NMIXX, IVE are so huge. StayC has jewel case verison also. Le sserafim is releasing the jewel case too.
This makes the physical sales not comparable. aespa has 3 versions but none of them are priced extremely cheap. Their jewel case i.e. synk dive is very expensive too. Kep1er also didnt have jewel case version.
Edit: Any way to split the sales by versions so that the 4th gen GGs sales are more comparable?
