Reposting this for those unaware of this pretty good perk by PayPal (with credit to nocure and others for previous posts). Stay safe, and enjoy :)
(1) Activate Refunded Returns. You’ll be eligible for a refund on return shipping costs from your next PayPal purchase.
(2) If you return an eligible purchase, log in to your PayPal account to find the original transaction.
(3) Submit a request with proof of return within 30 days of return and 150 days of purchase. Receive your refund, usually within 5 business days.
Do you have to reactivate this if you have before?
