Google Express is offering free delivery with $15+ orders.
"Today: Get free delivery on any store order of $15 or more."
For those seeking to use their Google Home $25 coupons, that's FREE SHIPPING. Normally $35 purchase required to trigger FS.
There may be some stores not participating in the offer.
At 14.90 ish you might get this message: "FREE delivery (You're close enough to the minimum.)"
UPDATE: This may be part of National Free Shipping Day which would make it today only. UPDATE: Still active on Saturday
