Cart Weight Alert

Take complete control of your store's shipping logistics and delivery margins with Advanced Cart Weight Alert & Management.

A common and costly challenge for Magento store owners is managing the total weight of a customer's cart during the checkout process. Often, customers are entirely unaware of weight limits and casually add heavy products to their cart. When it comes time to ship, store owners are hit with exorbitant delivery surcharges, or customers abandon their carts due to unexpectedly high shipping fees.

W3ctrl Advanced Cart Weight Alert solves this problem by giving you the power to restrict order weights and communicate transparently with your customers in real-time. Whether you need to enforce a strict maximum weight limit for your couriers, require a minimum weight for wholesale orders, or simply want to warn customers when their cart becomes exceptionally heavy, this extension handles it automatically.

Key Capabilities

• Enforce Weight Restrictions: Prevent checkout by setting strict Minimum and Maximum weight limits for orders. If a cart falls outside these boundaries, an error is displayed, and the customer cannot proceed until the cart is adjusted.
• Progressive Warning Levels: Not every heavy cart should be blocked. You can configure up to three dynamic "Warning Levels" (e.g., Level 1: 25kg, Level 2: 50kg, Level 3: 75kg). Each level triggers a unique custom message to warn the customer of impending shipping surcharges before they reach checkout.
• Dynamic Messaging with Placeholders: Create highly personalized, context-aware messages using dynamic variables. For example: "Warning! Your cart ({current_weight} kg) is {difference} kg over our standard shipping limit of {threshold} kg."
• Targeted Product Exclusions: Need to exclude lightweight items or digital products from the weight calculation? You can easily exclude specific Product IDs or toggle the inclusion of Virtual/Downloadable products via the admin panel.
• Flexible Display Options: Choose exactly where your messages appear to maximize visibility. Broadcast weight alerts on the Cart Page, the Checkout Page, and directly inside the Mini Cart. You can also define the severity format (Notice, Warning, or Error).
