I have 2 options, either
1. Complete car repairs ($700) and put the rest toward paying off Master Card
2. Pay off Master Card and charge some of the repairs on Amex and/or Visa.
That way I can have a zero balance on one card (to motivate me and perhaps raise credit score), and I can pay off the charge with my tax refund.
I know the smart thing is to use the cash to repair the car since I don't plan on buying a new one any time soon, but I would get a lot of satisfaction out of seeing a card with a zero balance.
What do you think?
