This is something I have only just learned how to do, and I am sure a lot of people didn't know it was possible because it isn't the most advertised feature and the PayPal interface isn't the most intuitive thing I have ever used.
- Log into PayPal
- Click View All My Transactions
- Click Find a Transaction
Easy! You can select by email, or name, or some others. Make sure you pick an appropriate date range and you will be flying!
