Well these are marketed as 16Gb.  parted is showing one to be 15.6Gb.  
And I have put over 8Gb on a couple of them.  I think if MicroCenter was 
seriously mismarketing them, their customers would be complaining in 
droves.  Being off by .4Gb would not be noticed and as in my cases 
tossed off as low quality that needed to mark parts of it as not to be 
used and thus the smaller size.
