Bank accidentally deposited extra $100?

-My bank account balance was $0. I went to the bank and deposited $100. I came home and just checked my account balance on the bank deposit receipt, it said I deposited $200. I went online banking and saw that they deposited $200 instead of $100.



Should I tell them? Or will they realize the mistake and take the money them self from my account?They should notice it at the end of business that day, as the teller whom waited on you will be short $100 and have to find out why. If it is not cleared up by the next business day I would call. Even if you spend the money, they will still take it out of your account, and you are likely to accumulate overdraft fees, and at an average of $31 each transaction, they add up quickly!They will probably pick it up. Just call and let them know because if you spend that and they take it out. Your in deep crap. On top of that keep your conscious clean. It's good practice haha.
Tell them, because they will eventually realize the mistake. If you spend the money, it can overdraw your account and accrue some major fees.
