Target team member here, any one in the East Valley in Phoenix, Target on Warner/Val Vista is probably the best store in my experience to find a good selection of clearance games, usually at 50% or less.
They are AS-IS because they shouldn't be carrying them any more and they have dropped out of the stores system. They get priced cheap to move out them out of the store. We just came across some HD DVDs two weeks ago and they got the AS-IS treatment for like $7.
Not sure what part but the street is E Peachtree I believe, should be temp until I can get my own place. I have a job in Tempe so it will probably closer to work.
I've been wanting to get out of Florida and my parents are headed out to AZ so I figured it was a great chance to try something new.
