These were listed for the last week as coming soon, and now they are in stock.
Based on the Pixel 5 & 4a 5G inventory last year, I expect these to go in and out of stock.
They do have a deal now to get a free pair of Google Pixel Buds, but if you do this deal, you can not apply the bring a friend referral.
The net cost of your first two months of service is the exact same: 2 month x $15/month = $30 v. $5 first month + $25 second month (when you do party pay) = $30, but your friend will not get one month of service for $5 too.
As predicted earlier above, the Pixels are now out of stock. Keep checking back to see when they add inventory.
The Galaxy S21 is out of stock too.
