Northern California Division has removed self checkout from a very low number of stores. I only know of one, and it just so happens to be the one nearest me in Sparks, NV. Other than that, Northern California has retained self checkouts and actually installed new Toshiba ones to replace the clunky NCR junk that they used to have in a number of locations. However, the newly opened stores the past couple years do not have self checkouts.
Conversely, other divisions have been removing self checkouts like crazy, which is generally not such a deal killer in low volume stores, but in higher volume stores, it is just a stupid move:
Portland Division: gone from all of the Southern Oregon Albertsons that used to have them under Supervalu
Intermountain Division: gone from the Elko Albertsons that used to have them under Supervalu
Southwest Division: gone from ALL of the Las Vegas Stores, and I didn't see any in the 4-5 Safeway locations I went to in suburban Phoenix last month either, also gone from those Southern Utah Albertsons which had them when they were under Supervalu
Vons Division: gone from the Bishop Vons and I have heard numerous others (really stupid move by this division)
