I can not select the carrier, is charging. What can I do?

To be able to choose the carrier you need to have the zip code with a green tick to acknowledge the shipping address and you can leave the carrier.

You can click in the box zip code if you already have stuffing and then in another part of the page, as well will turn green. If you get empty you must fill it in and click on any part of the page so that it turns green.
