How do I "lock" the bundles so that the customers cannot edit or delete some items from their cart before checking out?
Items from a bundle created in Bold Bundles cannot be locked from being edited or removed before the checkout. This is a theme customization that can be added from a developer or our Partners team.
If you would like to receive a quote for this customization, you can reach out to one of our partners such as ShopExperts or Storetasker.
