The way my figures are cast is in packs.
A mould with the tribal warriors yields 2 packs each time it is spun.
Great for selling packs.
However, when selling singles you hit problems.
I had a situation once where someone ordered 50 tribal archers.
Which meant spinning the mould 25 times, this then left 50 spare axe1, 50 spare axe2 and 50 spare spears.
I have still not recovered from this overstock.
It is the same with all the packs to some degree.
I am sitting on dead stock at the moment.
This is where you can buy the dead stock at reduced prices!
