I'm currently in the process of making a cake and don't have on hand the two eggs needed for the batter. I am forced to buy a dozen eggs (or if I'm lucky I can find a half dozen carton) at the grocery store. I'm at the mercy of the seller, just like this game.

As a side note, ever stop to think that you only see the large stacks because others have already purchased the smaller stacks? I actually sell flax in stacks of 10 or 20 for a higher per unit price than those selling stacks at 99. I also move those stacks quite fast.
