Each huge booster pack contains:
* 1 visible, non-random Huge miniature—pre-painted, fully assembled, durable plastic
* 4 hidden random miniatures—pre-painted, fully assembled, durable plastic
As my other half said, "What were they smoking when they decided to sell random assortments of D&D monsters? If I'm running a game I want 10 of X, 5 of y and 1 of z, not two kobolds and an intellect devourer."
Although apparently they've been selling minis for a while, and we've completely failed to notice, so something's not working too well in their strategy.
My other half buys minis. I generally don't. I don't wargame, and when we want them for more roleplaying purposes, I just print out little foldy paper things and use those. It's much easier to come up with something that looks right for the character or situation that way.
But to the best of my knowledge, an awful lot of mini-buying is the fun of modding and painting the figures to make your own cool stuff... *shrug* I dunno.
