The 100 pack TY at Supermediastore is currently selling for $35 (4x). But I am hesitant to buy because they don't come in a cakebox and according to the description they are version 2.0. What in the hell is a version 2.0? Anybody had experience with these discs? Not TY in general but this in particular. Is that like the Grade of the disc? Also, Rima and others don't sell the 4x anymore because they say that they were discontinued but now Supermediastore and Meritline are selling these. Any help will be appreciated.
