Recently, New York began requiring apps to tell you when prices were adjusted using personal data.

Now, most people probably read this news and thought, “Oh, okay, that’s fine. How different could the prices really be?”

It turns out, pretty different — and they change based on your behavior.

In the notice sent out to New York users, DoorDash admitted it uses “information such as your delivery address to calculate distance and fees.” That part is (mostly) fine.

It was the next part that customers took issue with. The notice admitted that “your past orders and favorite stores” are used to “provide personalized promotions and/or discounts.” In short, this means that DoorDash can look at your order history, guess what you’re going to buy, and figure out a way to charge you more for it.

Of course, that’s not how they’re framing it. They’re saying that, using your history, they’ll be able to give you customized discounts. However, we’ve all seen stores on DoorDash that appear to have perpetual discounts — who’s to say that DoorDash might see you like that store, then “experiment” with taking your discount away?

This kind of algorithmic pricing, on top of DoorDash’s existing fees, may help explain why prices on the app are so high. One study found that customers ordering from the app could expect to pay almost 40% more than if they had shopped in person.

But what am I going to do, stop ordering meal delivery? I have a job I need to pretend to be doing!
