This comes from the Wii GB over at IGN in this post (IGN Insiders only). A CC employee posted there talking about an email that was sent out with a $20 off $20 coupon for games/game accessories. His post:
I have a coupon for Circuit, I work there so I might as well share the wealth, that will get you $20 off any game or game accessorie priced over $20. This makes RE4 only $9.99 what an awesome deal! I can put up copies of the coupon if everyone would like, but they are kinda blurry. All that is necessary is the promo code because the people at the register can manually run it. The promo code is:
COU 70Y41SC00000015154
I hope everyone enjoys the savings =)

As far as using the code, the OP added that if you do bring the code to an employee, giving the letters COU is essential, as:
ooh, and BTW, the COU infront of the numbers is necessary, CC's register system needs a 3 digit for a brand or company before the code can be entered, any customer service person should know this but by giving them those 3 you are reassuring them that the code is real and making it less likely for you to run into trouble. I can't guarntee all stores will be as hassle free as mine so I appologize if they give you any trouble. I will get that copy for everyone asap though.
The thread is going back and forth waiting for the OP to get a better scan, but at least one person has reported going to CC and giving the code and getting it to work on a Wii game.
This might end up being nothing and is as YMMV as it gets, but I figured I'd post it here before SD/FW got it, as, if it is working, your best bet is probably to do it sooner rather than later in case CC shuts it down.
I'll post here again/update the OP if a better scan shows up.
