Right, I mean, for the "E" - what exactly is exclusive about it?
Soul Slabs, Vol. 3, is labeled with the "E", but will probably be repressed later on black vinyl. I'm not aware of any differences in the previous soul slabs comps' RSD editions and black represses other than the color of the vinyl.
I'm just noticing nearly everything I've even remotely considered being interested in is labeled with an "E," even certain albums that are just reissues, so it seems like they're being pretty specific in their idea of what makes it an exclusive. It would make sense that "E" just means "yeah, this version of it is only being sold for RSD, but it could definitely be repressed and reissued later in a different package", but it seems like you're saying that that's what "F" means. or does the "F" mean that they're doing a pressing run of more than what's available for record store day and there will definitely be a subsequent wider release of the rest of that run?
Like the Hot Rocks Rolling Stones comp is also labeled with an "E" - it sounds like it's a fancy color and comes with 2 fancy lithographs, but as an album, I'm sure they will keep repressing it later.
