Display the savings in the PrestaShop shopping cart
medseesaveoncart
Your customers add promotional products to their cart but don't realize how much money they are saving. As a result, they have no additional motivation to complete their order.
MedSeeSaveOnCart automatically displays the total amount saved directly on the cart, order history, and order details. It's a simple and effective psychological lever to increase your conversion rate.

The Problem
Your customers benefit from product discounts, promo codes and cart rules… but they don’t always realise it. The total amount saved is never clearly displayed anywhere in PrestaShop.
The result: customers don’t perceive the value of your offers, hesitate to complete their order and have no incentive to come back. You invest in promotions whose impact remains invisible.
The Solution
MedSeeSaveOnCart automatically calculates the total amount saved (product discounts + promo codes + cart rules) and displays it in a colourful, customisable banner.
Visible in the shopping cart, the checkout tunnel, the order history and the order detail page, it highlights the real value of your promotions and encourages purchase completion.
How It Works
Automatic Calculation
The module analyses the customer’s cart in real time: product discounts, promo codes and cart rules are summed up to get the total savings.
Instant Display
The amount saved is shown in a customisable banner on the cart and/or checkout page. Updates happen instantly via AJAX.
Loyalty
On the order history and order detail pages, customers see the total of their past savings, reinforcing their sense of getting a great deal.
