There are also sales on Verbatim media at the various internet stores as well as retailers like Office Max, Best Buy, etc. from time to time. Currently, Best Buy has one of the best buys [ironically], but after tomorrow the sale will probably be over, and deals on Verbatim rarely come around for the big retail chains.
Also, TY media cannot be found at big retail stores, so you will want to stick to the internet for that. You might be able to get results from Value Line stuff, but if you want guaranteed good results, go Premium Line.
You can always keep up with the latest sales by looking in the Bargain Basement: http://club.cdfreaks.com/f58/
Also, our old polls on media are still very relevant. They can be found in this forum. New poll[s] are upcoming, so watch to see how they go.
