Amazon just announced it's new Echo Dot today - it's a larger rounder version with a better speaker. It looks like if you buy a 2 pack you get $20 off of both (10/each).

So this brand new device - normally $50 is 80 for 2 if you pre-order
Also buy the 2 of the full-size Echos (normally $99/each) for $170 - Use Echo2PK
