Search and save. I do it for anything I buy online, especially PC stuff. I think I saw a U2711 for around $800 recently. That said, there's other monitors that are a bit cheaper and nearly as good. The Dell has all the fancy features/inputs, but for example the HP ZR2740W is a nice 27" 2560x1440 IPS monitor too.
Though I do agree with what rubix said, probably just a spam bot. I guess I'm bored.
