Does anybody know of an app similar to Multipacks but with a price auto-update feature? If the core product price is updated the multipack should calculate and update the price for the bundle as well. Thank you
Check out the app “Bundle Builder” on Shopify. It allows you to create product bundles, and it can automatically update bundle prices based on the core product prices.
Hi @Nimrod ,
This is Ellie from BOGOS (formerly Free Gifts by Secomapp), the #1 Promotion App on Shopify.
Try using BOGOS app, as it will calculate and update the bundle price accordingly even when you change the original price. You might need to wait for a min though.
