I never heard of the marriage penalty for couples without children! I was quite shocked myself. They also reward people who have kids.
Okay, so it is just a marraige penalty act regardless of if you have kids or not, but they do give you lots more money when you have kids. The first year I was married, we got back loads of money because we were not married the whole year prior, then, ever since, we have owed

As for the reward, or "extra" money you get for having kids...everyone tells me, "if you don't want to owe, have kids!". Okay, like the money you do get for having children covers the cost the children cost over the year. I don't think so. But I am going to have kids soon....I hope.
As for the HP boxes, I preordered 2. I want to get more, so if the release was really delayerd to May 12, when I get back from vacation, I may try to get some more. Especially if I win some money in the casino on the cruise ship!!!
