Glad you enjoyed it.
There should be enough SQL in the blog to re-purpose extracting out the Wildberries locations and seeing where they land on top of. I've never heard of this firm before you mentioned it.
From Google:
> Citibank operates over 2,300 ATMs within more than 600 U.S. branches, with a total network of over 65,000 fee-free ATMs
So the 57,163 Citibank locations are probably a combination of their branches and ATMs.
Update: I reviewed Alltheplaces a while back, they scrape company websites for store locations. They reported 68,227 locations for Wildberries. ATP is one of the sources Overture use but they seem to use 1.55M of the records from their 19M-record dataset. https://tech.marksblogg.com/alltheplaces.html
I'm a contributor for ATP and can confirm that the contributor of the wildberries spider was deliberately trying to collect https://wiki.openstreetmap.org/wiki/Tag:shop%3Doutpost (online order pickup locations). This is however not a common occurrence within the current set of ATP spiders to capture such features. A quick search indicates that OSM doesn't appear to have tags designed to capture pickup/dropoff partnerships between retail brands, for example, an agreement from a pet supply shop to allow collection of parcels from select fuel stations of a partner brand.
ATP has a much more inclusive set of features it can extract than what Overture Maps, TomTom et al care about. As Overture Maps is more opinionated on what they aggregate they will filter out ATP extracted features such as shop=outpost and infrastructure that ATP collects such as individual power poles, park bench seats, local government managed street and park trees, stormwater drain manholes, cemetery plots, weather stations, tsunami buoys, etc. I think there might be some exceptions if it helps TomTom et al with their products such as speed camera locations, national postal provider drop-off/pick-up locations within other branded retail shops, etc.
