Hello! would love recomendations on Page builder apps!
never used one before! My goal is to do somthing like this pictures:
Hey @VintBazar ,
you can achieve this using different apps.
Regarding the icon/text below the price you could find my app Bloom useful: https://apps.shopify.com/bloom-product-feature-bullets
My app can also help you with triggers such as “15 in stock”.
To add the “BUY MORE, SAVE MORE!” section, search the App store for bundle apps. You will find a lot.
Hope I was of help, let me know if you have more questions.

Inspect the page of the website and you’d probably see what page builder they’re using if they are, and then i guess go with that.
Normally go with apps focus on upsell and bundles, regarding the option for all-in-one app of page builder support similarly then I recommend EComposer I’m using. The app has its built-in extensions like Frequently bought together, cross selling,… support conversion so you don’t have to pay extra. Hope this help!
For the “Buy More, Save More” section shown in your screenshot, you won’t get that from a page builder alone. That part is better handled by a bundle app. Adoric Bundles fits well because it lets you add those tiered bundle offers directly inside the product page, no custom code needed.
