Hey, @willowsclothing . I noticed that you want to add “best seller” badges in your store.
We have developed an app (Modemagic) that will help you add badges and do other things (like automation/create and apply product labels/banners/feature cards etc) on your catalog within seconds.
And the best part is - No complex edits, no back & forth with designers is needed.
You can even reach out to us on chat for a custom design if you don’t find any of your interest from the wide variety that we have. Check out this app on Shopify here. We got a free trial as well so you can explore the app 
Hope this would help
