OH MY GOD
WALMART HAS ZUNE 80 FOR $138.54.
It's out of stock right now but check every 1 hour to 1 1/2 hour it goes in and out of stock. I got one already around 6PM.
UPDATE:
Alright so the deal is dead online but you can still try to get it in store. Go to any store, Walmart, Circuit City, or Best Buy and show them the webpage (see attachement). Tell them you want a price match and if you're lucky, you'll get it.
