Upselling is a sales technique where a seller induces the customer to purchase more expensive items, upgrades or other add-ons in an attempt to make a more profitable sale.

How it works?
When you view the product page, module shows products that are more expensive than the current one. Only products from the current category and child categories will be shown, so don't worry that wrong product will be shown.
Products are selected and displayed fully automatic based on their cost and module settings, so you don't need to bind products manually.
