Adding optional insurance service to existing shipping service This is my first question here, sorry if I miss something and for my bad english.
I have a D7 drupal commerce site, and custom wants to add an optional insurance for shipping. There is only 1 shipping service calculated with shipping weight tariff module. At checkout users should be ablen to choice wether buying insurance for shipping or not. If yes I should add 10% of order total with at least 10€ amount.

Thank you very much.
You'd probably add this using a combination of Rules (module) plus an additional custom field for Shipping line items.
