The thing is Celebration was not really that expensive back then. I mean, in general, I don't know the specifics of your case. I remember thinking "4LP for 40€, that's 10€ per disc" when I bought it (I was 16 and for me it was kind of a fortune so I had to justify it hahaha). But now it's different. Vinyl prices are getting higher and higher and I can't understand how they charge so much for so little.
The 6LP thing is hella expensive even without the shipping and taxes.
