What should you know before buying soju?

Last Sunday I was sitting with my friends at night. One friend talked about soju. He said it is a popular drink. That made me curious about it.

I went to a nearby store to check. They had a few drink options. Most were common drinks. I could not find many soju types. Options were very limited. I wanted to see different flavors.

To check more variety and options, while scrolling many online marketplaces including alibaba I saw many soju options. Some were fruit flavor. Some were original. There were many bottle sizes and styles. Prices were also different. It was easy to compare everything.

I also noticed some drinks were light. Some were strong. Some were for casual use. This helped me understand better.

Now I am thinking is it better to explore soju online for more variety or from local stores to check availability first?
