Just as an FYI...
The Ames stores here in Syracuse, New York periodically run a "30% off everything" sale, but there is ALWAYS a small blurb printed at the bottom that states "Everyday Low Price items are excluded from this sale."
I went back to the electronics department during their last sale, and noticed that the Dreamcast and PSOne had "Everyday Low Price" price cards above them but the Playstation 2 did NOT. However, when I attempted to purchase one, the register would not allow the 30% off. The manager stated that it was, in fact, an everyday low price item, and that the 30% coupon could not be used.
So, I'm not saying that the "Entertainment Guide" offer won't work, but I wouldn't be surprised if it doesn't.
