<prompt> Human: I am pretty set for cards, with Freedom and Sapphire Preferred from Chase. Credit limit is way more than I could ever use thanks to tips from personal finance, so I dont need more cards.However, I get about 3 envelopes a week from Discover, Amex, etc. asking me to apply. Amex Gold, for example, gives 500 signup bonus if I spend 1000.Anybody have experience taking the offers and then cancelling the cards after a few months? It seems like they are lossleading the cards with the hope that I would keep the card, so I could earn an extra thousand or so a year by surfing signup bonuses without repercussions.  <response>: rchurning
