I want to buy website theme
Hi there @hoanpham
You can buy a theme for your website from our theme store on this page. That being said, I would recommend taking a look at the free Online Store 2.0 themes to begin. You can find them listed here.
Once you’re ready to buy or add a theme you can click the Try theme button in the theme listing. This will add the theme to the theme library in your Shopify Admin. To purchase it officially you will want to go to Online store > Themes in your Shopify Admin and then click Actions > Buy next to the theme you want to purchase. You can read more about adding, buying, and previewing themes on this page.
What type of products do you sell? Are there certain features you are looking for in a theme? I’d be happy to help you select one. Please also let me know if you have any other questions about this.
