Total Revenue = # of Customers x Average Order Value per Customer

To lift up total revenue, one could choose to focus on driving new traffic or selling more to each existing customer. The Germany brand Amazingdealz already gets quite a decent source of traffic pouring in everyday, so they decided to concentrate on increasing the average order value per customers. That means, they aim to upsell & cross-sell relevant items so each customers will purchase more than they previously plan.

Instead of simply displaying related products, this Germany brand goes a little more tactical to trigger the preference for shopping with discounts from online shoppers. They offer a 15% discount on order over 50 EUR, and place personalized product recommendations based on what customers add into cart.

Take their most popular offer that have a 34.4% conversion rate for example: those who buy a hair and dirt filter for puppies will see a list of accessories for puppies, and an offer of 15% off if they spend more to reach 50 EUR of cart value.
They create lots of similar upsell offers like this for most items listed on the store. By upselling with gamification techniques, Amazingdealz successfully boost their average order value per customer by more than 4 times, and made 76,800 EUR of extra sales in 4 months.
