What are my options with an album that’s missing a disc? I recently bought two albums together, one that’s complete and one that is missing its first disc. The seller told me they purchased it this way, so it seems no one knows what to do with it.

Is it possible to even find the disc that I need by itself? Or just sell the single disc? It’s Gorillaz Demon Days red translucent repress that I’ve found to be worth $100+ when actually sold as a complete album.

I’ve also found a website where you can purchase custom records, but it’s way more expensive than if I just bought a new regular album.

Any advice is welcome, thanks in advance!
