Online or Physical Shops?

My friend and I are tired from visiting our deaf students but we had this feeling of fulfillment. After that, we went to the mall to wait for our friends who will be following with us.

We went to the mall as we waited. It's not air-conditioned though unless you'll enter the stores or shops. There are lots of stuff on sale but we didn't buy any because I'm more of buying online nowadays. Do you guys prefer buying online or in physical shops?
