If there was any doubt that Google's October 4th event will include a miniature Home speaker, Walmart just erased it. The big-box retailer briefly posted a listing for the Google Home Mini that not only shows off the puck-like Assistant device, but gives an idea of what to expect when it launches. The Mini will reportedly ship around October 19th for $49, and you might not even have to pay that much. You see, Walmart has an tie-in with Google Express that cuts $25 off the price of orders until January 15th. That means you could be paying as little as $24 -- not bad for a brand new alternative to the Echo Dot.
