An upsell in WooCommerce is a sales technique where you suggest a higher-value product to customers, typically displayed on a product page or during checkout. The goal is to encourage customers to upgrade their purchase by offering better versions, premium products, or accessories that complement the original product.

To add upsell products in WooCommerce, go to the product edit page in your WooCommerce admin. Under the Product Data section, click on the Linked Products tab. In the Upsells field, start typing the product name(s) you want to upsell, and select them from the suggestions. These upsell products will appear on the single product page, encouraging customers to buy additional higher-value products.

To display shipping costs on the product page in WooCommerce, you can use a plugin or custom code.

Using a Plugin: Install a plugin like WooCommerce Shipping Calculator on Product Page or WooCommerce Shipping Method on Product Page. These plugins allow you to show estimated shipping costs based on the customer’s location.

Using Custom Code: You can add custom code to your theme’s functions.php file to fetch and display shipping costs. This involves using WooCommerce hooks and the shipping methods API to calculate costs dynamically and display them on the product page.

Always test on a staging site before applying changes live.

WooCommerce offers several shipping methods to cater to various business needs. The main shipping methods include:

1. Flat Rate Shipping: Charge a fixed amount for shipping, regardless of order details.

2. Free Shipping: Offer free shipping on specific conditions like minimum order value.

3. Local Pickup: Allow customers to pick up their orders directly from your store.

4. International Shipping: Configure shipping options for global delivery.

5. Table Rate Shipping: Set rates based on conditions like weight, destination, or cart total.

6. Shipping Zones: Define shipping costs for specific geographical regions.

7. Real-Time Shipping: Integrate with carriers like USPS, UPS, FedEx to fetch live rates.

These methods can be customized using additional plugins for more complex requirements.

For UPS shipping in WooCommerce, the official UPS Shipping Method extension from WooCommerce provides real‑time UPS rates at checkout based on address, weight, and shipping services. It’s reliable if you just need live UPS pricing. For more comprehensive features like label printing and tracking, plugins such as PluginHive’s UPS Shipping Plugin or ShipEngine/EasyPost integrations let you fetch UPS rates and handle label creation directly in your dashboard. Another versatile choice is a multi‑carrier shipping plugin that includes UPS alongside other carriers, giving flexibility and automation for shipping logistics.

One of the top USPS shipping solutions for WooCommerce is the USPS Shipping Method extension, which connects your store to the USPS API to show real‑time domestic and international rates at checkout. It supports services like Priority Mail, First Class, and Express, helping customers see accurate costs based on weight and destination. Another strong option is ELEX EasyPost or USPS Live Rates plugins that fetch live USPS rates and can include label printing and tracking features. Alternatively, WooCommerce Shipping Services integrates USPS rates along with other carriers for automated label printing and streamlined fulfillment.
