Don't forget for tax planning purposes that these bank bonuses are 1099-INT income! Some banks may hit you with a credit inquiry when you open, so you might want to look that up if you are sensitive to this sort of thing. Be aware of what you need to do to avoid fees while you await the minimum time the account needs to be open to receive the bonus, or after receiving the bonus to not have to pay it back. Other than that, no gotchas of which I am aware.
