There's two coupons on that page. One is for 30% off the list price of one item -- the other is for the specific titles. You can't get an additional 30% off of the sale price of Transformers.
I haven't been in a Borders in a while. How are their prices on Blu-ray and HD DVD--I'm curious how they compare to prices at, say, Amazon (esp. during the B1G1 sales), as I just bought a Blu-ray player (and already have the HD DVD drive addon for my Xbox 360), so I figure it's time to start expanding my HDM collection? Do they even carry HD DVD and Blu-ray in their stores?
Other than Best Buy, the Borders in my area easily has the best high def selection of any store around.
Granted, that just means that they have more than the ten or so HD DVDs and Blu Ray discs that Wal Mart and Circuit City have but second place is second place.
And here's a coupon for Buy 1, Get 1 Half Price on HD DVD and Blu Ray. No doubt it will get its own thread here and two threads in the HD section as well.
