<prompt> Human: I signed up for an Amazon Store Card ASC today, because I shop from amazon quite frequently, and the 5 from ASC was better than the 1 from my Costco Visa. Within 30 minutes I learned that there is an Amazon Prime Rewards Visa Signature Card APRVSC that offers 5 from amazon, 1-2 at other places, some goodies for traveling. Am I in error and what are my options? How will my credit score be effected with perhaps cancelling the ASC and switching to APRVSC?  <response>: Dont cancel. Just apply for the new credit card. I have both, it is no big deal.
