One of the most common ways through which both physical stores and e-commerce stores get more orders is by bundling products together and providing the customer with a discount. This can actually be a bit tricky in e-commerce if you don't set it up correctly. You'll most likely want to count the products independently for accounting, inventory, and reporting purposes. That's why there's a Product Bundles extension that handles all of that stuff while the customer just sees a product and the Buy button.
You'll need to have installed and activated the Product Bundles plugin available here: http://www.woothemes.com/products/product-bundles/. You should also have at least two simple products in your store.
In order to add a product bundle, carry out the following steps:
- From the WordPress admin, go to Products | Add Product.
- Give the product a name in the Product Name field.
- Scroll down to the Product Data pane. From the drop-down, select Product bundle.
- If your products are packaged separately, check the Non-Bundled Shipping checkbox.
- Enter a price for the bundle in the Regular Price ($) field.
- Click on the Bundled Products tab.
- Under Bundled Products, type in the products that will make up the bundle.
- Click on Save Configuration.
- After the configuration is saved, you can click on each component and adjust several details such as the quantity in each bundle. Adjusting these details is optional.
- Publish your product and take a look at it from the frontend of your site.
You'll want to go back and add a featured image, and possibly an image gallery, for the bundle. It's really helpful to show the user exactly what they're getting in the bundle so make sure the featured image shows all of the items in the bundle.
Bundles are one of the more common ways of combining products, but there are other ways. For a full guide on the many ways of doing this, see the comparison article at http://docs.woothemes.com/document/chained-products-vs-product-bundles-vs-force-sells-vs-grouped-products/.
