If you're in the US, the best place to get TY media is http://www.rima.com, bar none. $30 for 50 8x +Rs. Madness!!!
And if you buy 1,000pcs you can get them for $0.55 each....
Actually, it's $0.55 each if you buy 100 pieces, not 1,000. That's not a bad deal at all! I paid $75 for the same thing just a few weeks ago from them. For whatever it's worth, I've ordered several times from them and they always have shipped the same day and everything was handled very well. In fact I just ordered some TY CD-R's from them today, and an hour later got a shipping/tracking confirmation.
Ahh... I have a friend who ordered 1,000pcs, and got $0.55ea on them, so I figured that was the price break point. I have alternate sources, so I don't tend to buy any blank media retail anymore, and sometimes don't get all the facts on the current deals, since I have little to no personal experience with them.
