Well let me say this 2 weeks ago you could still get MITSUI 8x GOLD 650mb 25 pcs for 5 euro at iwonatec. Which delivers also to germany. Clearing there stock.
THey are offcourse no longer there. (No I didn't buy them, I did thought about it but I have still to much cd-r's arround)
And I also still have some YUDEN000T01 Samsung (good bonded ones, The bad I allready threw away. ). And I can still get new YUDEN000T01's Maxell ones.
And yes I can still get 8x TY's branded.(150 pcs stock at this moment.)
Infact it seems that I still have access to a lot of weird stuff but in most cases it does have it's price. Which is the reason why you can still get it.
People don't like paying (much) more for something that in there eyes looks inferior (lower max writing speed or smaller capacity !)
