I haven't found any specific information about instance configuration and region deployment for Walmart. But you are absolutely correct, Spanner is quite expensive.
I assume Walmart has a custom-tailored contract with much better rates that are visible in the GC calculator (https://cloud.google.com/products/calculator). Plus, they definitely use multi-year reserved instances. On a three-year contract, it's 40% lower price.
Ah yeah I bet they have a special contract. There is this article about Pokemon Go [0] using Spanner, which states that they have 5000 nodes any given time.
The pricing calculator will not even calculate this, as it is limited to 4k nodes which costs $12,724,800.00/ mo with the 3 year usage discount.
Spanner is just great, yet expansive. Do you know how many nodes Walmart uses?

I enjoyed reading this. The accuracy is amazing, thanks to the TrueTime API.
Thanks for the shoutout, Samuel!
