I'm looking at a Pixel 6 (not Pro) with 128 GB and the options I'm seeing are BestBuy, Verizon, Amazon, and Google Store.
BestBuy has limited color choices, Stormy Black, Sorta Seafoam, and Kinda Coral, and according to their website there are no stores with 250 miles of me (Minneapolis) that have them in stock. Delivery is not available. Unlocked version. Price is $599.
Verizon has limited color choices, only Stormy Black and Sorta Seafoam, and there are 2 stores where I can pick it up. I presume this is the Verizon version. Price is $699.
Amazon has it in Stormy Black. Price is $599. Can't get it before Christmas though.
Google Store has Stormy Black, Sorta Seafoam, and Kinda Coral, and the unlocked version is $599.
Seems like it's Google Store for the win.
