Fantasy Flight Games have sent along details of a correction to the pricing for the Wings of War WWI Series 4 miniatures.
From their announcement:
It has come to our attention that there was an error with the pricing of the Wings of War World War 1 Series 4 Miniatures (WW23a-WW23l). This change will effect all orders going forward and will not effect any order we have already received.
The MSRP for WW23g-WW23l will now be $15.95. These are larger two seat planes and is inline with the pricing of the other series of planes.
