Hi all, does anyone see any benefit from having a social media account to promote your listings? Like an Instagram page with a link in bio to Etsy or Tik Tok shop? Any success stories or is it too much faff

Im so happy with my first sale, but now im not sure what to do next. On Print shrimp it went in production this morning. So now i want to complete the order on etsy. I don't have tracing information yet. The order must go to United States, how do i know what shipping carrier to select? And what date?
