PayPal partial refund glitch
We’re hearing that some sellers may have problems performing partial PayPal refunds. Sellers who routinely refund excess postage are most likely to stumble across the error as they naturally will process more refunds.
The error doesn’t appear to affect all refunds, but if you run into a problem refund trying again several hours (or even days) later probably won’t fix the issue. We’re told that PayPal are aware of the problem and are resolving issues in batches.
You may well ask why people are refunding postage, but it’s still a common occurrence when buyers make multiple purchases and either don’t use the eBay shopping basket or are purchasing from abroad and the eBay shopping basket simply isn’t available.
