Circuit City online coupon YMMV

Ok so I put a Blu-Ray player (from another deal, the Sony for $200) in my CC cart to see if I could use a coupon code on it. It wasn't eligible though. Then I exited and thought nothing more about it. Today I get an email:

"We hope you enjoyed your visit to CircuitCity.com! Looks like you've found a few things you're interested in, so we saved them in your cart.

Got your eye on something special? Use this $15 coupon for your next online purchase. "

Good for $15 off $100 or more. I got the email about 24 hours after. So if you can wait 24 hours, sign up for a CC account if you don't have one already, put the item in the cart and wait for the coupon to roll in. Another interesting thing is that the coupon code field at the checkout was starred out ****** . Good luck.
