Main shopping street downtown

Hey 👋 So i’m an international student living in Spring and I’m thinking about going downtown today. Last time I was told to go to Main Street for shopping but that street was huge and I ended up walking for about 2 hours without seeing any stores except for 1 (my flaming heart I think it was called)

I don’t have a car, I’m taking the bus. Can anyone recommend a bus/train stop to get off?

Any help is very much appreciated, Thank you 😊
