In WooCommerce, you can set different shipping rates using Shipping Classes. Go to WooCommerce → Settings → Shipping → Shipping Classes and create classes like Heavy, Light, or Fragile. Assign a shipping class to each product from the product edit page. Then open Shipping Zones, edit a shipping method such as Flat Rate, and set costs for each class. This lets you charge different shipping rates based on product type or weight.

To add a single product to a page in WooCommerce, use the WooCommerce shortcodes. Add the [product_page id="product_id"] shortcode to your page or post, replacing “product_id” with the actual product ID you want to display. Alternatively, you can use the “Product” block in the block editor to add a specific product directly to your page. After publishing, your product will appear on the page, including its title, price, and description.

To enable free shipping in WooCommerce, go to WooCommerce → Settings → Shipping → Add Shipping Zone, then add a Free Shipping method and set conditions like minimum order amount or coupons. To integrate USPS, install a plugin such as WooCommerce USPS Shipping Method or Flexible Shipping for USPS. These plugins allow real-time shipping rates, tracking, and label printing. After installation, configure your USPS API credentials and shipping options in the plugin settings. This setup helps automate shipping costs and improves checkout accuracy for customers using USPS or other carriers.

The WooCommerce checkout is the final step where customers complete their purchase. It collects billing details, shipping information, and payment method. After reviewing the order, the customer places it. WooCommerce then processes payment through the selected gateway, creates the order, reduces stock, and sends confirmation emails. A smooth checkout experience helps reduce cart abandonment and improves sales.
