I think they eventually got as high as $12/CD.
The original Dischord releases had labels or stickers on them that said something like "Do not pay more than $5 for this cassette" and I think it was $8 for CDs and LPs. And this was in record stores. At first the price tag always reflected that but over the years a lot of places stopped giving a shit. It was always sadly hilarious to see a Dischord CD in a store with "Do not pay more than $8" on the cover and the store's price tag showing $10.99.
I just took a look at my '95 CD, Inzombia by Slant 6 and even that late there is small print that reads "$8 post paid in USA from 3819 Beecher Street NW". I also have some re-issue CDs from the early 00s. The Minor Threat Discography says "This compact disc is only $12" in the notes. Others say "$11 post paid..."
