Superache Vinyl?

Hey I was wondering why the superache vinyls are so difficult to find or if they are available they're so expensive? Superache's my favourite Conan Gray album and I just recently got a record player and wanted to get the vinyl. I've checked his store and it only has the cd and cassette for me (I'm uk based). Does anyone have a reliable place I can get them please? If they're sold at shows I'm supposed to be seeing him this weekend so I could get it then
