Most people here seem to be pulling money from their checking accounts. Why not an interest bearing account?
We pay our cc bills from our Cap One performance savings account and earn interest on the balance.
I use a checking account that does earn some interest, the reason I don't change is mostly inertia. It would be a hassle to change all my auto-pays Although I have rent pulled from my Fidelity account because the cash earns 5% and the landlord takes his sweet time in cashing the check.
