I bought mine. I'm sure you can get them in random packs as well, but I think if you want to make progress in the game, spending a couple of Hive in the marketplace makes sense. You probably don't NEED 5 of them, but I was finding a lot of pizza when I had just used the first 15% of my energy from a previous pizza, and that felt wasteful. Even with 5 pizza boxes, I am finding a lot of pizza "in the wild" when all of my boxes are full, so energy hasn't been a problem for me at all this weekend.
