I will pay via G&S from now on, and likely use Escrow.com to safely manage transactions for significant amounts.
When selling, I will use G&S with PayPal vendor protection, and still use Escrow.com for significant amounts.
I will do everything according to PayPal rules, so that they have no recourse against me.
I will however likely link to a bank account with more limited funds in it. I prefer using a bank account to a credit card, as my bank provides excellent customer service and is easy to work with (unlike most credit cards). They immediately reversed these fraudulent charges, with little bureaucracy. Mind you, I have been a loyal customer for 40 years!
