Lumia 521 for $79.95 at Amazon (Price drop! Now matches HSN.com price)

Lumia 521 (Amazon)

This is the lowest I've seen it, except on HSN.com which also has it for ~$80. HSN.com includes a generic car charger and case, which I guess gives it a slight edge over Amazon's deal, but I'm more comfortable buying from Amazon.
