You've probably heard that it's a bad idea to finance a big purchase with a credit card. And yes, if you don't plan on paying that purchase back all that quickly, you run into the danger of interest fees and suddenly that Black Friday deal doesn't look like such a steal after all.

HOWEVER, if you do plan on paying that balance back right away, then paying for a big-ticket item with a new 0% interest card that also offers a cash back bonus as part of its signup incentive could save you as much as $100 on that big purchase. Here's how it works...

The cash back credit cards below include 0% interest on new purchases for anywhere from six to 15 months, depending on the card. They also include a $100 cash back incentive when you spend a certain amount on new purchases within a specific amount of time. Essentially, if you open one of the below cards and make a $1,000 purchase within your first three months as a cardholder, they'll reward you with a $100 statement, check or gift card, again depending on the card. Simply by using one of the below cards for your big purchase, you're saving yourself $100. Pretty good deal, right?

The below credit cards to finance a big purchase also include extensive 0% interest intro periods applied to purchases. We NEVER recommend hesitating to pay back your balance in full, but the extended intro period attached to these cards give consumers time to pay back those big-ticket items in incremental amounts if necessary.
