In Drupal 7 Commerce 1.x - is there a way to include the price into the dropdown product select box?
Include the price in the product title itself in same way which you want to show in select box.

There are other way, in that you will have fetch the product id of the product reference field in template.php &amp; load full product to get price. Then prepare title again at theme lavel..

For better understanding of what I am talking about, you can see my answer for a question here, where I have explained how to prepare title of node again which include taxonomy. You also have to do something similar like that..

But I will suggest you to follow the first solution of mine means - Include price with title of the product.
