Your zip code is a level of security embedded in to our ordering system on behalf of the customer and their security. Your zip code acts, not unlike a pin code, to verify the card and billing details you have entered.
If you are receiving an error message, please contact the bank that issued the card you are using to complete payment. Once you speak to them please verify their information on file for that card. Then ensure you are entering the zip code they have provided for that card, in the billing address section, the last page of the checkout. This will allow you to post payment and complete an order.
Please also note sometimes, bank cards can take up to two weeks to process new changes.
If you continue to have issues with a particular card, please know we also accept payment, using any already set up and verified account with an external payment processor such as Paypal or GooglePay (although these are not required or necessary to use).
Please know we accept all forms of any verified and current Debit/Credit card such as; Visa, MasterCard, American Express and Discover.
