Did this trade successfully. Split into two serperate trades of 50% each. Not quite sure why but all went well.
Paypal does not have buyer protection for payments that were sent in more than 1 complete payment. Therefore, if you pay for a good/service in 2 or more separate payments, you wouldn't be covered under the buyer protection. However, AFAIK, this is only for purchases of goods/services, not for friends and family. But it's paypal and you'd want to be as safe as possible
