Kin bollocks! I was lucky then! I have also used Shipito once. That worked.
I linked up my joint bank a/c with Paypal OK. I think I just pretended it was mine (my name was first), never volunteered that there was a 2nd a/c name. So far that has worked for me as I suspect that they only usually match on the first few characters af the account name & I have a long surname.
Anyway, Brian, you can use your wife's paypal a/c to pay, and the payment will go through to the same bank account and credit card. Won't she tell you her password?
So if you can get that password you're just a concierge service short of an order...
