I have been buying CD's on that auction site for a few months. It is my observation that CD prices are now slowly ascending. The price of vinyl is pulling them up. Slowly, but surely.
The cost of LP's and CD's - an observation
Back just before CD's, Albums were usually around $6-8.00, cutout less, double albums a bit more. When CD's first came out they were 'premium' items and cost $10-15.00, slowly the prices for CD's came down and records slowly all went down to a buck or two then disappeared. Now it's reversed, CD's are a few bucks, new Albums are usually around $15 to 25.00. (I didn't figure out the inflation rate, someone else can add that in) . And those cutouts can now be worth a small fortune. I just thought this reversal was interesting. Of course with Streaming, music of any quality is very cheap.
