The Good Guys seem to be clearing out their stock of the now older 2nd gen Amazon Echo.
The $39 price matches what is on Amazon.com.au, but doesn't seem to include a free cover as you might get with the other deal here: https://www.ozbargain.com.au/node/419071
Seems as though there's a few stores in here in VIC with stock. So if you don't want a cover and don't have prime, this could be another option.
What about 2 x Echo Dots for $49, https://www.ozbargain.com.au/node/422312
