Child of Eden was on sale yesterday at $35 on Amazon as part of their deal of the day. I went ahead and ordered it, it's close to what I was willing to pay for it.
Then I learned that Gamestop.com was selling the game for $30, which was what I was willing to pay for it. Sheesh, just my luck...
... oh well. If you were waiting until it was $30, click here. It's an online-only price, though. And according to this relevant GAF post, you should enter VSHIP at checkout for free shipping.
I'll get my copy next week and will review it when I get the time to.
