I've recently become fed-up with Bank of America (When they charged me a $10 overdraft fee the one time in 2 years I used the wrong card at the wrong time and all they did for that $10 was transfer money from my savings because I had overdraft "protection"). Anyway. In the course of looking up replacements, I discovered Fidelity reimburses ATM fees and seems to have no such overdraft charges for in-account transfers.
I already use Fidelity for my 401k and individual brokerage account so I'm pretty attracted to this idea of using Fidelity and dropping any standard "bank" account. I need routing/bank account numbers for a few bill payments and electronic payment deposits so I checked and they seem to support numbers which map to your brokerage account (https://www.fidelity.com/cash-management/deposit-money/determine-routing-and-account-number).
So at this point I like the idea - drop bank accounts use my brokerage account like one. One place for everything; free ATM withdrawls, no overdraft craps.
My question is...am I missing something? is there a drawback? And can I really use the account number (see link) in all places i can use a bank account?
