Payment and Ordering

Changing an Order

We try to ship orders immediately after they are placed, usually within 1 business day.

Once an order is submitted it cannot be modified. If you need to make a change, please call us at 314-205-3033 and we will assist you with canceling and replacing the order.


Canceling an Order

An order may be canceled at any time before shipment.

Please note that even if you have not received a shipment email, your order may have already been shipped.

Once orders have been shipped, they cannot be canceled, but may be returned under our return policy.


What credit cards do you accept? 

We accept all major credit cards, including:

  • Visa
  • Discover
  • Mastercard
  • American Express


Paying By Check or Money Order

We accept personal checks and money orders. Please check out, and select "Check/Money Order" as your payment method.

The name on the order must match the name on the check.

You will receive instructions on where to send the payment via email. Your order will be shipped once we receive the payment.

Please do not send cash in the mail.


Paying with PayPal

We currently accept Pay Pal. If you have any questions or concerns, please feel free to contact us.


Can I pay using two different payment methods or two separate cards?

At this time, we unfortunately cannot split payments between two payment methods or credit cards.


Using a Prepaid Card

Our system should accept all prepaid credit cards or gift cards with no issue. If you experience any problems, please contact us.


Saving Credit Cards at Diode Dynamics

Diode Dynamics does not store any credit card information directly on our servers.

Card information is stored via Braintree, one of the largest credit card processing companies. Using a Vault integration, any saved card option is displayed on our site based on your login.

Any expired cards are automatically removed from our system.


Order Confirmation Email 

When you place an order on our website, you will get an automated order confirmation email within 10 minutes of ordering.

If you do not get an email, please check your spam folder.

If you still cannot find the email, it is possible that the order was not placed, or that you mistyped the email address.

Please send us a message or call 314-205-3033 to check whether or not we received your order.


Placing an Order Over the Phone

Our staff would be happy to help you place an order over the phone anytime during our normal hours, listed below.

When ordering over the phone, please be sure to mention any coupon codes or free items you wish to receive with your order. To expedite the process, we do not normally ask for these items.
