AV Fest?
If you are willing to buy something outdate a bit... yes... CHEAP.
If you wanna get stock overrun things... YES. Very cheap.

Other than that, do your homework first by going to shops and scout around for what you really need and what you wanna buy. Get the best price and wait until AV Fest. On the day, go back to those shop and bargain again.

What is cheap there? Audiophile CDs are cheap if you know which one you need.
