For example, Safeway (and the rest of the Albertsons stores) offer coupons that are only available online. You use them in person in the store, via the loyalty card, but you have to use their website or app to get them. Some of these get offered to everyone, but others are personalized based on whatever data they have on you.

Seriously, once you realize you’re paying a minimum of 30% extra, it becomes hard to stomach.

Depends on what you mean. I can buy groceries directly through the grocer instead of a middleman like DoorDash. I would count that as online.

Many grocery stories were also experimenting with digital signage that is dynamic as well. So many not individually profiled but at level of hours/neighborhood. They are trying to bring it where they can.

A lot of grocery chains let you order online. They'll pack it for you and you simply drive there and pick up (they'll bring to your car).
