I saw an ad for this a few years back. I started one, and then I had my husband start one. It's our emergency money, our 'let's go on another vacation' money, etc.
We meet the qualifications every month.
But that reminds me.....one of the 'hoops' we jump through is having my paycheck direct deposited there. If/when I'm no longer working, we'll have to have something else to replace that automatic transaction. We have the cable bill come out of his account to satisfy that part of the requirements.
Besides the interest part, they reimburse ATM fees. We only use an ATM occasionally, but we never have to think twice about the fee.
