First Mistake: Going to Wal-Mart
Second Mistake: Asking about video games there
Third Mistake: Believing what the people there, who obviously know nothing about video games, say.
Solution: Go to GameStop, or EB, or whatever you have around where you live. You can pre-order games there, and get a coin. And they know what they're talking about.
Oh, and Galaxy's coming out on November 12th.
