Cheap as chips

I dropped on a bunch of used SD cards for free, mostly 8GB with a couple of 4GB . 
Didn't have cases with them but a quick look on eBay and 10 of them were winging their way to me. 
I didn't expect the plastic to be up to much but  it turned out to be fine, no different than the expensive stuff. 
How cheap were 10 SD cases including shipping from China?  
How does $0.99 grab you? 

Ah well. Until tomorrow....
