From the announcement:
The VFM WWII Mystery Bags are back!
Select either the German or U.S. Mystery Bags and get 10 random figures of that bag type for only $16.50. What you get in each bag is a complete mystery, hence the name, but what is not a mystery is the fact you will get $30 dollars of figures for $16.50.
