What is the difference between upselling and cross-selling?
I have read that the app is perfect for both upselling and cross-selling. What's the difference?
When you upsell, you are pitching and selling products that are of higher value or an upgrade of the product being discussed while when you cross-sell, you are trying to sell similar products to the one in question, or products that are related to it. Discounted Upsell works for both
Can I get the app for half the price since I will just be cross-selling and will not do upselling?
Cross-selling and upselling are not two functions that can be separated. It is what you prefer to offer to the customer. It is not possible to install the app and just one of the two functions.
