Refund & Shipping

Last updated: 6 October 2026

This page explains how orders, delivery and refunds work for products from The Engineering Projects (TEP) shop.

How to order

Online checkout is not available yet. To order a product, email info@theengineeringprojects.com with the product name and your country. We reply with the final price, the payment options and the delivery details before you pay. Prices in our shop are shown in US dollars.

Delivery

• Digital products, such as e-books, files and libraries, are sent by email or download link after we receive your payment.
• Physical products are shipped to the address you give us. We tell you the shipping cost and the expected delivery time before you pay; it depends on your location and the shipping method.

Problems with an order

If a product arrives damaged, is not what you ordered, or a digital file does not work, email us within 7 days of delivery with your order details and, if possible, a photo or screenshot of the problem. We will replace the product, fix the file or refund you.

Refunds

• Digital products can be refunded if the file is faulty and we cannot fix it.
• Physical products can be returned in their original condition within 7 days of delivery. Unless the product was damaged or wrong, return shipping is paid by you.
• Refunds are sent to the original payment method once we have approved the refund or received the returned product.

Custom projects

For custom engineering projects, the price, delivery time and payment terms are agreed by email before work starts. See our F.A.Q..
