Fluid Power Engineering 1st Edition

All Novabooks products are digital eBooks delivered instantly by email after purchase. Because the nature of digital goods does not allow them to be "returned" once accessed, all sales are generally considered final once a download has been opened. However, we stand behind every title we sell and will always work to make things right.

You are eligible for a full refund or a replacement file in the following situations:

• The downloaded file is corrupted, unreadable, or incomplete.
• You accidentally placed a duplicate order for the same title within 48 hours.
• You completed your purchase but never accessed the download link (within 7 days of purchase).
• The file is materially different from what was described on the product page.
• A technical issue with the download link cannot be resolved by our support team.

How to request a refund: Simply email us at novabooks.shop@gmail.com with your order number and a brief description of the issue. We respond within 24–48 hours, and approved refunds are processed back to your original payment method within 5–10 business days.

For complete terms, please read our full Refund Policy.
