<prompt> Human: Looking to make a sizable furniture purchase for a new house so not much cash laying around after down payment. Is it better credit score wise to open a new 0 store card or use my existing card that has 16 balance? The balance would be paid off in a few months so the interest wouldnt be a lot.  <response>: Paying any interest sucks. If you dont want to go the frugal route and buy secondhand furniture, Id go 0. Why lose money?
