There is a cheaper deal if you wish to buy only 1 USB.

BUT!
If you want to buy more than 1, this is a better deal!
2 x 16 USB = $19.90 + Shipping ($5.93) = $25.83 /2 = $12.92 each
3 x 16 USB = $29.85 + Shipping ($7.90) = $37.75 /3 = $12.58 each
4 x ….
and so on…
Apparently really, really bad speeds…
EDIT: The TL;DR is 'worse than USB 2.0'.
