KGB Burgers at Harrahs

Was looking through my older papers from Las vegas and ran across a 2 for 1 KGB 2 for 1 burger. I pulled up the site http://twitpic.com/24zzi and the only coupon that comes up is like the one I have expired 10/31/10. Does anyone know if there are any coupons available now with a good date.

The coupon booklet that they give to you on check in at a Harrah's property has a 2/4/1 for KGB that's good until March.

I checked into Harrah's LV last Saturday and there's no KGB coupon in the coupons they gave me. These coupons expire April 30, so they've changed what they're giving out.

Must be only at some of the properties then. My son gave me his and he checked into Rio on 1/5/11 and then joined us at Wyndham Grand Desert on 1/7/11. We used it on 1/13/11.
