My bad. It's a crap deal. My apologies.
Lowe's has a $20 store gift card with mail-in rebate after purchasing a Google Home Mini for $39, bringing the total to $19 plus tax. This matches the price before the holidays, with the caveat that the gift card must be used at Lowe's.
The $20 gift card is also available with the original Google Home, but at $129 better deals can be had elsewhere.
