These amounts seem insignificant. I already have a BOA checking and savings account, so maybe I should just sign up. In fact, I already have a debit card from them. But I almost never use it, as I tend to use my Delta AmEx for everything. Even still, I only make maybe 20 credit card purchases per month. Say each of those purchases has an average roundoff total of 50 cents. If I switch all of those to the debit card, I'll be putting a grand total of $10/month into the savings account. For three months, BOA would match that. Okay, an extra $30; not bad. But after that, they match 5%. That would be 50 cents per month? That hardly seems worth it. I think I'll stick with the FF miles...
