Depends. I almost always buy clothes and shoes in actual stores, as shopping for them online is a wasteful hassle. There are also some shops that I enjoy visiting, like second-hand stores or Asian supermarkets, where it’s interesting to just browse and buy interesting things I wasn’t specifically looking for.
On the other hand, I always buy stuff like electronics online. Electronics stores are more expensive and have a way smaller selection, so I don’t bother with them. Generally if I’m looking for something specific, buying it online is just more convenient.
