When it comes to branded credit cards offered by stores or gas stations, they most likely are not affiliated with a payment network like Visa or Mastercard and therefore, they cannot be used everywhere. As for the Kwik Trip credit card, it is good for shopping at Kwik Trip / Kwik Star gas stations and stores only. You won't be able to use Kwik Trip card outside Kwik Trip locations. So, if you'd rather prefer a credit card that can be used everywhere, we would recommend you to skip the Kwik Trip card and apply for a regular credit card instead.
