If the shipping method does not appear after you fill your shipping details chances are that you filled it wrong. Please check again. If you find your input correct and the shipping is still not available, then it is in a format not accepted by the logistic companies (mostly FedEx). Don’t use slash / dash / space in the ZIP code and don’t use any special signs. Clearing the cache of the browser might help too (switching to another browser or anonymous mode should be enough). If the problem still persists, contact the support with a screenshot of the page.
