NIB high dollar stuff (LE, premiums, JJP, etc...) is dropping.
NIB pro stuff is taking a normal hit. Keep in mind that many people were buying NIB pros just 2 years ago for $42-4500 and then selling for 5k to match the newest title. Reality is setting in now.
If Stern adjusts down for PRO pricing then it shows they are adjusting to lack of demand. If not, then there are still enough dummies out there.
Aside from that, prices are still going up on all the classics and good games form the 70s, 80s, and 90s.
I buy mainly old stuff, rare stuff, and sub 2k so my buying habits wont change.
