They are going up in the Bay Area, California, too. Goodwills and other thrifts have gone from their LONG standard 99 cents to $1.99. The dollar bin at one music store is getting increasingly less populated. Once the mostly $2.49 LP's are now 3.99 - $4.99's are $6.99, and so on. Plus, you don't find those mint first pressings as often for a dollar. The staff is getting more careful to weed out based on condition, pressing, etc.
You can still find real values at the thrifts (I found a mint first pressing Buckingham-Nicks two weeks ago for a buck), even they are getting wise. Where I live you NEVER see 50's/60's jazz at the thrifts unless they are TRASHED. Someone is sifting through and selling them elsewhere. I have no real problem because the money goes to those that need it much more than do I need a cheap record.
Still, even at $7.99 for a NM LP, it is cheaper and better than CD's, and FAR cheaper then buying some of the new re-releases. Here is one reason for us to HOPE that vinyl comes back strong. More sales will mean cheaper unit prices, eventually.
