Don't know why you wouldn't. I'm sure you're aware that you can feed them more than one item as they progress (2 - 3 per feed). This way you'd get value for money and use all of the bulk buy before progressing onto the next stage.
Hey @Bl69aze, Remember when we were talking about colour and pattern variations in Carpets. Well these two little wild guys above come from the scrub behind my place that starts about 30 meters from my back fence and are an excellent example of how they can vary even within a very small area.
15 more mouths to feed, these little terrors are very animated straight out of the egg and 30 secs after this photo they started going in all directions, by comparison the albino Darwins are like worms and just stay still.
