Walmart still offering the Google Home Mini in chalk or charcoal bundled with a $25 Walmart Credit for use on a future order on Google Express for $29 for a limited time. Shipping adds $5.99 or pad your order to $35 for Free Shipping or even opt for in-store pickup to dodge shipping altogether. The Walmart credit will be issued when you link your Walmart account to your Google account. If you plan to use the store credit, this effectively makes the Google Home mini only $4. Limit two coupons per household. Credit expires January 15, 2018.
