I would wait a few days before I worried too much about that. I got a similar email for something a few weeks back and they sent me a shipping conformation email the next day with tracking information saying it was shipped before they sent the email.
Finally found a sale with a decent selection of games. Managed to get all this for $20:
NES
Excitebike
Yoshi's Cookie
Galaga
Top Gun
SNES
Super Mario World
The Legend of Zelda A Link to the Past
NBA Jam
Secret of Evermore
GBC
Pokemon Crystal
PS1
Spyro
Lunar Silver Star Story...
If you can find it at Best Buy, there is a $10 Game Club coupon which should knock it down to $20. Here the link:

Some new guides pennied at Blockbuster. I managed to pick up:
Street Fighter IV
Metal Gear Solid 4
Mortal Kombat vs. DC Universe
Super Smash Bros. Brawl
Checked GTA IV but it was still $10.00.
I just went to Best Buy and picked up Bionic Commando and Need for Speed for a penny. All of the other guides listed were gone along with Red Alert 3 and Fallout 3 regular edition. I checked Fallout 3 CE and it still rang up full price. Hope this helps.
