My haul for today:

Green Lantern Steelbook
Clash of the Titans Steelbook
Wrath of the Titans Steelbook
Superman Triple pack
The Woman in Black

When I went to check out the girl only the scanned my coupon once and I had to tell her to do it for each Bluray, obviously not knowing how the U&S works she then gave me back my receipt and coupon. Guess I will be going back without having to trade in anything.
