That\'s an excellent return for a savings account.
I figured out that at my bank (which is paying less than 1% on savings) I earn about 10 cents per month on a $500 balance.
I do better for myself keeping an eye out for dropped pennies on the ground each month.

And to think that so many people think so little of pennies these days. It all adds up.
Will the account that you opened continue to pay 10% on the first $500 each year?
What\'s the interest rate on the rest of the balance?
Any limits as to how much can accumulate there?
What happens when DD is older than their \'kids only\' rate allows for?
