I found this in my email inbox today:
You’ve activated Return Shipping on Us, where PayPal will refund up to $30 of return shipping costs for eligible purchases.
We’ve recently made some improvements to this free benefit to your account:
More refunds
You are now eligible to receive up to 12 refunds per calendar year (between January 1st and December 31st)
More time to file
You’ll have 30 days from the return shipping date to file your refund request, up to 150 days after you made the original purchase
More time to follow up
Once a claim has been filed, you’ll have 14 days to follow up with any required documentation or information that may be missing
We’ve also made it even easier to file a refund request on our website.
