Sony, Maxell, and Verbatim (MCC) media in UK

Came across this in some business talks.
Maybe not the cheapest media, but surely some of the best.
Ranges from 25-40p per disc.

The problem with that website is that the value per disc is only applicable if you buy 500 discs. You can see it if you select the drop down menu on the right. I do quite fancy the maxell for masters though :)

Yeah, I did notice that. But even then, the prices for 100-200 discs wasn't horrible. Equiv of about 75 cents per disc for some media that's not necessarily easy to find in the UK. For making masters, that'd be in my budget. Most of my mastering discs cost me about 50-100 cents each.
