At this time, we do not have a feature in the Lulu xPress App which allows for creating bundles. This can be achieved through the use of a third-party app, however, and there are several Apps available in the Shopify App Store which will allow you to sell products as a bundle. Important: While Shopify vets apps used on their site to ensure they meet certain usability standards, this does not ensure that other Shopify Apps or third-party Apps will function correctly with Lulu xPress. We strongly advise placing a test order prior to making a bundled product live, and if you experience errors or unexpected behavior from Lulu xPress, we suggest testing Lulu xPress with all third-party apps turned off. Please note, if two books are ordered in the same transaction by one customer, they will ship together, regardless of whether they are bundled in your store’s listing.
