Ecommerce platforms vet the apps and plug-ins used on their sites to ensure they meet certain usability standards. This does not ensure that other apps or plug-ins will function correctly with Lulu Direct. Prior to using any apps or plug-ins alongside Lulu Direct, we strongly suggest creating several test orders first to ensure the app or plug-in is compatible with Lulu Direct.BundlesAt this time, we do not have a feature in Lulu Direct which allows for creating bundles. This can be achieved through the use of a third-party app, however, and there are several apps and plugins available through ecommerce platforms which will allow you to sell products as a bundle. 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.If you are utilizing a third-party app or plugin for bundles, upselling, or anything else, and are experiencing errors or unexpected behavior from Lulu Direct, we suggest testing Lulu Direct with all apps and plug-ins turned off or disconnected.
