Once an order is cancelled or refunded, sellers can relist their item directly back onto Reverb. 

Step by Step Guide:

1. If your order was refunded, head to your Refunded Orders page. If it was cancelled, navigate to the Cancelled Orders page.

2. Find the order, then select "Relist" on the right-hand side.

3. Review and confirm your listing's details. If the condition of your item has changed since the original sale, it's important that you update the listing form accordingly.

4. Click "Save & Review Listing".

5. Publish your listing.
