Drupal Commerce : Shopping Cart Checkout for Orders What I'd like to do is have an order page where the user see's a list of all products.  

They'll then fill out the quantities they want and click on 'checkout'  . 

So it'd look like how the Cart looks once you've added products



Has anyone done this or anything similar.   I'm currently looking at using Drupal commerce on Drupal 7. 

Much Appreciated.
My initial thought is for you to check out the commerce_add_to_cart_extras module.  Granted, it's still in its dev version, but you can create a view with products, specify quantity, and bulk-ly add to cart.

To go straight to checkout, you may need to add a little redirect in the submit handler for that button.
