I don't know how long their deals last, but they seem like the kind of place that would honor it if you mentioned it. I also suspect they buy close-outs in bulk - I was told as much about the speakers I got for my home theater from there - they bought a bunch of S505's (or something) which retailed at $1400 and are selling them for $600. Off topic: they were 5 satellite speakers and TWO powered subwoofers, and they're pretty amazing.
