There are several offers right now that I don’t think are going to last. Some we know won’t. Others banks have hinted they won’t. And in some cases we can make that bet based on past experience.
Usually there aren’t this many heightened offers at once, it’s an embarrassment of riches, largely I think because it’s getting harder and harder to get consumer attention, banks need to spend more to acquire customers and it’s a highly competitive environment, when one product increases its offer others respond in kind.
