“Rewards” checking, which My Money Blog explains (via Get Rich Slowly), smells kinda gimicky and designed to encourage spending over earning. And the ten to twelve transaction requirement is kinda a deal breaker for me.
I tend to put most expenses on credit and always pay that off within grace (which buffers my cash flow a bit). And on good months, I try to be frugal and average one or two card transactions a week. I kinda think limiting how many transactions you make per month (if you can in your situation) will save you more than what you gain on a notched up interest rate.
Checking for me is a local credit union affair with premeditated spending or scheduled electronic bill pay on stuff I can’t put on my credit card, like, uh, my credit card bill.
What the credit union next door does not provide is a high-yield savings account or equivalent vehicle for that three-month reserve.
