The Target mobile app is more opaque about this.

If you have accepted location permissions for the Target app, the app will show the in-store price when it can tell you're in a store.

The only way of knowing this is that in smaller/lighter print under the price, it'll either say "Online" or whatever store location.

The most egregious example was an item I bought that cost 40% more in-store versus online, and you'd never know had you looked at the app.
