It's the principle, but 50 cents adds up fairly quickly if it goes on too long.
And if it were to go on for a month, or a week, I'd completely agree that it's a very serious problem needing to be more properly addressed.

If it goes on for 2 or 3 days right at launch... I'm annoyed. Everyone's annoyed. I get it. But we can rage all we want, and it won't make things better. It'll just help us annoy ourselves more. If it's truly a matter of principle to you then I would genuinely say you should ignore my sarcastic last sentence and actually go try to get your 2/30th of 15 dollars back. If that makes you feel whole, more power to you. For what it's worth, I agree you're entitled to that refund. Otherwise, until/unless this becomes a longstanding issue, I really think that being "zen" about it is probably the best thing you can do to keep yourself happy. If someone disagrees and thinks that venting on here is more helpful, I certainly can't (and won't) stop them. Just saying though. Rage usually just leads to more rage, rather than making one feel settled.
