Oh that's easy, gotta show of those new models of course!!
So in go the Demigryph knights for 33,50
We'll also add in a box of Greatswords for 25,50 because they're so cool.
Add in a box of Infantry and Shooters each for 15,50 a piece and there you go!
90 quid of stuff they can sell for 70, giving you a 'battalion' of 33 models in total.
