At Kodiiac, we're always trying to make it easier to shop and purchase your favorite gear at the best prices. You can now login and pay with your Amazon account after completing your order at checkout, so there is no need to set up another account.
Here's how it works.
Option 1: When you are ready to check out, go to your cart and you'll see a yellow "Pay with Amazon" button on the right. Click on it and sign into your Amazon account and you're all set to pay using your secured Amazon credentials.
Option 2: If you go directly to checkout, you will go through the checkout process, click pay with Amazon, complete your order and then sign in to your Amazon account to pay.
