Gift Wrap Option Ubercart 3 on Drupal 7 I would like to add a global gift wrap option to our checkout pane on Ubercart 3 (running on Drupal 7).

It is an option that can apply to any product and has a fixed price no matter how many products are purchased.

I do not want to add it as an attribute to individual products or product classes, but would like to add a simple yes/no radio button to all checkouts.  If yes is selected, the fixed amount is added to the order.

What is the simplest/best way to implement this?
Another approach would be to create a Gift Wrap product class.    Create a node of this custom type with the price of your gift wrap option.     Then create a view of the custom Gift Wrap entity and display it prominently as a block on your cart and checkout pages.
