We do not currently offer Walmart credit cards, but you can apply for the National Credit Direct card. This card allows you to shop online at nationalcreditdirect.com, where you can buy electronics including HD TVs. The card charges an annual fee and an application fee. Your credit activity may be reported to the major credit bureaus, which will help you improve your credit. This is not a MasterCard or Visa credit card, so you won’t be able to use it anywhere but at nationalcreditdirect.com.
