<prompt> Human: I signed up for the Chase Sapphire Preferred in March and am ready to add a new card to my wallet. Im looking at the signup bonuses offered by CC but they all seem to be the same since the last time I researched them in march of this year. I was wondering if companiesbanks change their offers over time and if I should wait for them to do so before I apply for any new cards. I apologize if this a terrible question.  <response>: rchurning
