Monster Cable Z-Series speaker cable deals

Monster Cable is good stuff, right? Just overpriced, you say? How about getting 70% off?

Monster Cable Z-Series Z1 10 ft/pair speaker cable (terminated with spades) @ 70% off

Monster Cable Z-Series Z1 10 ft/pair speaker cable (terminated with banana plugs) @ 50% off

I have seen these at $100.00 for 10 ft pairs @ my local Good Guys chain before they went of business (purchased by CompUSA, which is also going out of business). These are not your regular old Monster Cable.
