Ha! Also just did this yesterday with my Fidelity Visa - a very quick phone call and I no longer have this due on the 9th of the month. Seriously, the 9th?

YMMV, but I haven’t paid any fees with the one account I have at each bank. This might be a fluke with Mango (not complaining), but you definitely shouldn’t incur any fees with NetSpend assuming you follow The Finance Buff’s instructions I linked to and only ACH money in and out. Let me know if you’d like a $20…

Conversely, if you don’t mind jumping through a couple hoops, you could stack several NetSpend and a Mango savings accounts earning 5-6%. Once I get my student loans paid off, that’s my plan: $35-40k in liquid cash earning an outsized return in FDIC-insured accounts.
