It depends on the condition. I got a couple of albums in very good condition for $4 and $7. I also got a double album that was pretty rare, in vg+/near mint for $20, a great deal to me. I found the prices here much more reasonable than Amoeba or some other places. If you are more flexible about condition, you can get albums for $1-3. I was impressed with price and quality.
Vinyl prices vary a lot, from $1 to over $20.
