Uh during a 0 apr period I thought that's what most of us do. To hit above your weight/budget w/o consequence, or for cash flow… which is the business way of saying the first thing
Saving money should always be more important than your credit score. Carrying a balance on 0 APR helps your timing then so be it. You use chase cards, you earn ur no matter if the bill is paid or not. Even if you were late on a payment you don't lose your points for the most part they just gobbled up 35 bucks in a late fee
