Had a code for Free shipping went through the process and never saw that it could not ship to Hawaii, placed order and was charged 17.99 additional for shipping. The customer service said it was because it needed to be sent by air but they still sent it USPS. They do not charge extra for Shipping to Hawaii or Alaska. If you send a letter all you need to do is add a stamp they won't charge more if it's going by air. Ridiculous
