If you can get BFV priced match and have a red card, use the Target app to pay. Add your red card to the apps wallet. When you scan to pay it'll also scan coupons you have on cartwheel.
This worked for me when there was a coupon for Crash and I had it price matched.
I tried an account I already had, but never had premium on it. It allowed me to do the trial and I signed up for the family plan. But I didn't get the email about the Google Home. Unless its really delayed. Or the account I used isn't eligible?
Does this not work if you already have a Walmart account? Cause when I entered it, it said does not apply to that order.
EDIT: Never mind I read the original post and see it does not.
