Safeway's use of data is comically bad. Since 2010 or so, I've been signed up for their Just4U special discounts, based on what they know about my shopping habits, as a California dad. Recently they offered me a bonus coupon for Pampers diapers. Not a match! Our kids have been out of diapers since the days when BlackBerry was the coolest phone in town. Maybe longer. I'm not impulse-buying diapers for anyone else's kids. They let a week go by and then offered me a special deal on Depends, the old-people's diapers. Not in my current need list either. Another week goes by, and they come up with a third idea. This time it's a discount coupon for Kotex sanitary napkins. Hello? They've got about nine years of regular shopping data on me. If they still make multi-decade errors in identifying my age -- and can't get my gender right -- their data department hasn't even made it into the abacus era.
