Refunds

If a file is broken or wrong, email us and we will send a fixed one.

If the workbook will not open or work in Excel 2021 or later, including Excel 2024 and Microsoft 365, on Windows or Mac, we will refund you in full if you ask within 14 days of purchase. Tell us which version of Excel you use and what happens when you open the file. We may ask for a screenshot so we can fix the problem for other buyers.

The workbooks are not built for Google Sheets, Numbers or LibreOffice. They may work there, but we can't promise it, and a problem in those apps alone is not a reason for a refund.

Because the workbook is a download, we don't offer refunds for a change of mind once it has been downloaded. If you bought it by mistake and haven't downloaded it yet, email us within 14 days and we will refund you.

The free Lite workbook costs nothing, so there is nothing to refund, but please tell us if it doesn't work.

Refunds are issued by us, the seller, through PayPal, not by Payhip. If you contact Payhip about a refund, they will send you to us. The refund goes back to the card or PayPal account you paid with. Your bank may take several days to show it.

This policy does not affect any rights you have under the consumer law where you live.

To ask for a fix or a refund, email help@marginrule.com with the email address you used at checkout and your order number from the Payhip receipt.
