Is this writing good so far?

I think it's good, but you need to work on making it cohesive. For example, she yells at him out of nowhere. One minute she's thinking about shopping and the next she's yelling. In order for that to make sense, she'd need to be irritated in her thoughts first. You're writing is great, but I don't get a feel for your personal style, try doing some free writes to evolve as a writer.
