Keep in mind the difference between brand and manufacturer. Here in the media forum, we tend to talk more about manufacturers, since that is a much more reliable indication of disc quality than the brand that is printed on the disc or box.
A disc sold in the store as "Fujifilm" brand, for example, could actually be made by several different companies, Taiyo Yuden, Prodisc, and CMC, for example... and of these discs from the different manufacturers, some are good, and some are to be avoided.
You can get some good deals buying retail (at the "big box" stores like Best Buy, Staples, Officemax) but you have to pay attention to the country of origin on the package (Made in Japan is good, Made in Taiwan could be good or bad, for example) and you're never 100% guaranteed that the manufacturer of the discs you buy is the one you want... or you can buy online from reputable dealers like rima.com, newegg.com, meritline.com, and be sure of getting the manufacturer you want.
Taiyo Yuden makes some of the best discs out there, but you won't see their name in any retail stores in the US. You'll have to buy certain brands that say "Made in Japan" on them, or buy OEM discs online.
Hope this helps.
