Redirect to the Checkout/Cart page after adding to cart
Sometimes we need a quick buy option. It works like, when a customer adds products to the cart, it automatically redirects to the Checkout or Cart page. You can control that option from the 'Configuration' tab.
If you using 'Selected' add to cart option
Then use Bundle Quick Buy option.
Or if you are using the 'Add to Cart' button, then use the Quick Buy option.
