<prompt> Human: Thinking about getting an AMEX Blue card that gives 200 for signing up. Would it be bad to redeem the 200 after 3 months and then cancel the card after having it for a total of 6 months? Sounds like this is called churning and not too bad to do but Im 23 and have a limited credit history but am in good financial position to take advantage of these sort of offers - just not sure what the impact if any on credit might be.  <response>: rchurning
