I order to cancel a listing on eBay that is tied to an auto relist profile, navigate to the active listings page. On the page, you should see a link that says, "Stop auto relist" next to the active listing.
This will stop auto relist for this particular listing. You can then go to eBay and cancel the listing without it having auto relisting.
The only thing it keep in mind is if you post the original listing again and it is still tied to an auto relist profile, it will auto relist. By stopping auto relist from the active listings page, you are only turning auto relist off for that listing.
