While on a shopping spree, you open credit-card accounts at several of your favorite department stores to snap up discounts of 10% or 15%. You’re saving a bundle, but you may be chipping away at your credit score.

Part of rebuilding your credit is proving that you can pay your bills on time. If your bad credit episode left you without any credit cards, you’ll have to open new ones.

If you don’t have an established credit history, or if you do have an established credit history but it has some dings, you may need a co-signer to get approved for a loan or credit card. By co-signing a credit application, the co-signer is agreeing to assume responsibility for the debt should you, the primary borrower, default on your agreement to pay the debt.

Sometimes, people make bad decisions and they end up losing their house, car and credit cards that ruin their credit history.

If your credit history isn’t all that long or spotless, adding a credit account with a long, positive credit history to your report will certainly boost your score but how do you all of a sudden add an old account to your credit report?
