I'm the owner of a smartphone gadgets store. I'm creating the app to sell the gadgets through the app. I have just one question. I would like that when a user adds a specific article to the basket, the app suggests other specific articles this user could be interested to buy. exp: The user adds an iPhone Charger to the basket then the app should suggest adding also an iPhone cover.
Yes, it's possible. I use the Recommendation plugin for those kinds of upsells. There are more ways to do that. It's like the "you may also like" suggestion some online stores have. You can suggest one or multiple articles or you can also suggest a category.
