<prompt> Human: I am low on cash and would want to open up a credit card to purchase something. It would be paid off right away within a month as I do have incoming cash from ebay its just that something goes on sale soon so I wouldnt have the money right away.I will 100 pay off the card, and plan on cutting the card up the moment its been used for that said item so that I dont do anything dumb. Id be closing it right after its paid off... within a monthIs this a horrible idea? Will it affect my credit score? And for the record, I only have 1 credit card, I pay it on time but its nearing its maxAssistant: More info: I am 22 years old. The max limit on my card is 1200, Im at around 1k. I need 600 to purchase something, Ill be getting around 800 on ebayI read that canceling a credit card affects your credit in a negative way, but was told since I only have 1 credit card and Im young dumb it wouldnt affect me too much since its not like Im buying a house or car any time soon  <response>: How about not buying the thing... At all? And using that incoming 800 to almost fully pay off your debt with the CC company?You could also see whether theres a cheaper version of the thing around or whether there are second-hand options of buying the thing or a previous version of the thing.
