I think NOVA was asking about the discs with the packaging similar to the packaging shown in the attatchment in the above post. In that case, the only configurations you can buy are the singles in jewel cases, 10-packs with jewel cases, 10+1-pack in flip case, 20-pack in spindle, and 50-pack in spindle. These discs are all RiTEK-made.
However, TDK Gold discs, which are CMC-made, come in singles, 5-pack with slim cases, 10-pack with jewel cases, 10+1-pack in flip case, 25-pack in spindle, 50-pack in spindle, and 100-pack in spindle configurations.
Hope that clears things up!
