I've done a a bit of business on Ebay but this is the first time I've had this:
Taken from my e-mail received from Paypal:
You've received a payment, detailed below. We've placed a temporary hold on the funds for this transaction.
eBay and PayPal are working together to make it safer than ever to buy on eBay. One of the boldest steps is to identify transactions that pose the greatest risk of fraud and holding the payments from sellers for a period of time to help ensure that the transactions go smoothly.
We'll release the payment for the eBay item if either of the following occurs:
The buyer leaves you positive feedback on eBay.
It's been 21 days since the payment date and you haven't received a dispute, claim, chargeback, or reversal on the transaction being held
Additional hold period
If you receive a dispute, claim, chargeback, or reversal on the transaction, we may hold the payment until the problem is resolved.
