Hi. How can we Help?

We have had strong demand during the pandemic and appreciate your business and understanding as work to meet your needs while supporting our employees in these difficult circumstances. Answers to a few common questions are below.

When will my order ship?

Many orders are still shipping the same day! In some cases your order will ship the next day, with some taking a day longer. Freight carriers are experiencing delays with equipment and staffing as well. Please allow an extra day or two for transit.

When will you get my item in stock?

Many of our suppliers and vendors were completely closed for a month or more and are still regaining their production capacity. Coupled with very strong demand, we are working hard to expedite key items and parts. Items are coming back into stock daily, but it will take some time before our inventory and stock availability is back to pre-pandemic levels. Our websites are updated daily and remain the best spot to check availability and expected re-stock dates.

Online Ordering

Online ordering remains the best way to place your order with Horizon Hobby. If you need help with ordering, making a return or have questions that can’t be answered using our website information, please contact websales@horizonhobby.com

Technical Support

Many common product and support questions are available online. Please reference our Tech Support Page. If you need additional support, please contact our product support team using chat or email. Due to a strong surge in volume and the impact of the pandemic, our response times are taking longer than usual. Your patience is appreciated as our team works through your requests.

FAQ's to find answers to our most common questions:

I can't get the promo code to work.

Your promotional code may be expired. Please refresh your screen by clicking the F5 key or go to our home page to see if the promotion is still active. Once we deactive a promotional code we can no longer apply it.

Do you ship outside the USA?

Horizon Hobby values it's customers all over the world. The option to ship orders outside the USA may be temporarily unavailable but watch for the return of this feature very soon! In the meantime, stay safe!

Did my order go through?

You will receive an email confirmation if your order was successful. If you see that your payment was authorized but you didn't receive an order confirmation, it's probable your order was successfully placed but the connectivity to feed the confirmation to your web account and email failed. Please allow 24-48 hours to watch for the order to ship out. These are unusual situations but can happen.

I made a mistake and need to make a change or cancel the order.

It's important that you check the details of your order prior to submitting it to us. At Horizon Hobby our goal is to process your order quickly. One of the first steps in our warehouse is to print your shipping label and your packing slip. Because of this process, we are unable to make any changes to an order that has already printed in our warehouse. This includes adding, subtracting or changing items as well as changing the address on the label, merging or cancelling an order.

I can't track my package or my package is delayed.

We will send a confirmation email with your tracking information. If you were charged for your order but have no tracking number. Please make sure the email did not go to your junk or spam filter. Even if a package is delayed by the shipment carrier, the cause for the delay is typically worked out in just a few days. Packages must be confirmed missing after 10 days before we can take any action on a replacement or refund.
