You can buy a bank login with a password and access to e-mail in verified account stores in this section:
Accounts, Logs.
But keep in mind that it will have a zero balance (fresh or used). Carders who have received bank logs with a balance and access to e-mail cash it out themselves and do not need to sell such accounts.
You can buy just a login with a password, then log into the account and change the e-mail to yours through account management or call the bank (you must provide the owner's full info).
Talk to the owners of the logs who receive them using a stealer, perhaps they will have what you need.
