VPCART “Product Bundles” enables merchants to create a
bundled product out of several other products. The bundle appears in cart as a
separate product alongside all the items in the bundle. 
The cart remembers
which items are part of a bundle and prevents removing items individually. The
bundle carries the price and weight in the cart. The products from the bundle
carry zero weight and zero price. We can say the bundle is a product with its
own price and weight although it contains one or more products in the
bundle.
The price in the cart is not the total price of the items in
the bundle.Instead, it is exactly retrieved from cprice of the
bundle.
Bundles do not have stock. The stock will be deducted from
individual products inside a bundle automatically.
To manage your product bundle, you can go to administration
page : Store > Product > click Bundled tab.
To add a bundle, click the Add a Record button at the top of
the page.
To edit a bundle, click the Edit button next to the bundle
you wish to change.
To delete a bundle, tick the box next to the bundle and click the Delete Selected Records button.
