I do. My paypal is linked to my personal account, and Mr. Bee's paypal is linked to our joint account (they don't let you use the same bank account for different users). Mr. Bee does not have a personal account though.

I only use my personal account for paypal, and don't really need it, but am holding onto it. I've had it for 15 years after all.

Do you have a personal account and a joint account? Does your SO?
