To put it lightly, we wouldn't recommend you to ever get a Sears credit card, not to mention any other store credit cards. Sears offers discounts or special financing for a short period. However, this special financing option somes with a price. It's called deferred financing. You are really going to get a 0% intro APR offer for some time, but after it ends you don't have to pay interest on the remaining sum. You'll have to pay the interest on the balance starting from the say of your first purchase, and and it may result in tremendous sums. So, we sould strongly advise against it if you have the slightest doubt you'll be able to pay off the balance on time.
Speaking about other options, there are plenty of them. General credit cards with 0% intro APR give you special financing for much longer periods than store cards. Besides, if you are unable to pay off the balance within the intro period, you'll have to pay the interest only on the remainder. Here, on our site, you can find a wide selection or credit cards with the 0% intro APR offers, and they even come with generous rewards on your purchases. For example, the Discover it® Cash Back card gives you up to 5% cash back in rotating categories that change throughout the year (up to the quarterly maximum each time you activate), all other purchases earn 1% cash back, and a 14-month 0% intro APR period on purchases and balance transfers (14.24% - 25.24% Variable after that). If you are a frequent traveler, take a look at the Discover it® Miles. With this card, you will earn 1.5 miles on all purchases and will get 14 months 0% intro purchase APR. When the introductory interest rate is over, the ongoing APR of 14.24% - 25.24% Variable will apply. For both cards Discover matches all the miles or cash back you earn for the first year of card usage (only for new cardmembers).
If you are looking for longer promo periods, there are also credit cards for you. The Citi Simplicity® Card - No Late Fees Ever gives 12-months 0% intro APR on purchases and 21-months 0% intro APR on balance transfers (when the introductory interest rate is over, the ongoing APR of 16.99% - 26.99%* (Variable) will apply), the balance transfer fee is 5% of each balance transfer; $5 minimum. That's more than a year without any interest - an outstanding offer for shopping at any stores. Don't forget that all of these cards work at any store, Sears and all others too.
