Fumiup is right.
you have to make sure they are made in japan. forget about that 100% certified and certified plus stuff. it used to be that certified plus were taiyo yuden (excellent) and 100% certified were ritek (POS). now, TDKs are all 100% certified. so you have to make sure of where they are made in.
i bought the 100% certified 100pk from costco. they are taiyo yuden according to cdr identifier. (link to program:
CDR Identifier)
most of buy.com are made in taiwan, so they are riteks.
here's the link to tdk's rebate (i used this instead of costco's):
TDK Rebate
as for the upcoming costco sale, it will only last one week (late feb). that is a discount taken at the register so you can still do the mail-in rebate.
does that answer everybody's questions?
