It's a mix but in general I'll just use apps during the week and on weekends try to go out to physical stores.
The one exception is shopping for clothing which I always go to a store to do. I'm not great at judging how shirts/dresses/whatever will actually look on my body so it's easier to just go in person. Plus it's an excuse to hang out with some of my friends and do girly things.
Always going outside because 1. i live next to a grocerie store 2. you can see if they have discounts 3. i would like to see what im buying before i have it.
