I have 4 games with slipcovers and
all 4 have different bar codes (and other codes)
for the slipcover and for the game box inside it:
- The Witcher 3
https://vgcollect.com/item/204194 has the description "originally a part of the The Witcher 3: Wild Hunt slipcover release".
https://vgcollect.com/item/204195I know this game is sold without the slipcover as well, but I can't confirm if the bar code of this version is the same of the box inside the slipcover.
- Cyberpunk 2077
https://vgcollect.com/item/206705 the only version submited here, I can't say if this game is sold without the slipcover
- Terra-Média: Sombras de Mordor
https://vgcollect.com/item/204164 the only version submited here, but I had a previous box without slipcover with this exact bar code, and now I have a slipcover version with the same bar code on the box and a different bar code for the slipcover (I don't know if my previous version was sold originally without slipcover, I bought it used)
- Sonic Mania Plus
not submited yet, I can't say if this game is sold without slipcover
As I said, I can't confirm that all games are sold with and without the slipcover with the same bar codes, but I have a game that I guarantee that I bought it new and sealed without the slipcover:
https://vgcollect.com/item/238893but I discovered it is sold in a version with the same bar code for the box that comes inside a slipcover that have its own barcode

So, is it ok to submit the two entries like The Witcher 3 with the description saying it is part of a slipcover edition?
If the text is confusing, I can elaborate further.
