Paypal are great for buyers but worse than useless for sellers - just read warwickhunt's post - but even then, someone ripped me off as a buyer and Paypal did nothing for 8 weeks. I eventually got my bank to refund me. Then Paypal decided they'd give me half the money back. Still not good enough, but since my bank coughed up, i actually refunded Paypal.
Why you have so much trust in such a gang of cowboys as Paypal, is weird
Transferwise are far more trustworthy. If the seller sends you a pile of poo, then i would contact my bank.
