That's a 50% increase. If this was the real world, there'd be a revolt. Then again, a virtual Stitch hat went for over $300 on an online auction this weekend, so I guess anything's possible!
Regardless, as long as people will mule for prizes and be rude for prizes and falsely report one another for prizes, I know I won't be parting with that many credits any time soon! It's a shame, too, because I'd love to design a quest.
C'est la vie!
