Not sure that just having 6 - 8 fig sets alone, can lower the selling price ... as the savings would perhaps be limited to packaging only. Additionally some themes, such as WWII do not readily support bulk offerings as the individual action poses vary greatly.
On the other hand, themes such as NAP, AWI & Alamo more readily support bulk offering as these usually involve movement/fighting in lines, columns & squares.
It has been suggested that perhaps if K&C were to offer ... say 4 figs standing & firing ... their angle of their arms may vary, or if one was hatless, or if one had a moustache, or if one had a torn uniform ... it would involve using one basic mould and running a higher production volume on a single piece.
Now this should be able to reduce the average selling cost ... as well as presenting diomakers/collecters with a more creditable/realistic formation of troops.
This formula is used successfully by other manufacturers ... but if it works, I believe IMHO it should not stand in the way for K&C to adopt a similar approach ... for lines such as the NAPs, AWI, Alamo .. or say the marching WWI, LAH etc etc.
I also understand the call for more melee figs in the NAPs & AWI series .. and personally, I would be prepared to pay slightly more for such individualistic poses, compared to a more generic standing at the ready or standing firing.
