Can widgets be used for upsells and cross-sells on Shopify?

Yes, widgets can be used for upsells and cross-sells on Shopify. Upsell widgets suggest higher-priced or premium versions of a product your customer is viewing on the store. Personalised cross-sell widgets show complimentary items your customers might also like. For example, if a customer adds a phone to their cart, a widget can suggest a case or screen protector as cross-selling.
