Getting ready to drop some cash on back-to-school shopping? Consider applying for the Capital One® Quicksilver® Cash Rewards Credit Card, which offers a one-time $100 sign-up bonus for new customers who spend $500 on purchases within the first three months. In addition, this cash-back credit card earns 1.5 percent cash back on all purchases, regardless of category or merchant.

Instead of requiring multiple trips to office supply specialists and discount department stores, Quicksilver lets you streamline your shopping. Eliminating featured categories means you can hunt for the best deal at any retailer you like, online or at brick-and-mortar stores. When you're ready to cash in your rebate, you won't even have to wait for the end of your statement cycle. Capital One's online "purchase eraser" tool gives you the power to request statement credits just days after your eligible transactions have cleared.

This card, which charges no annual fee, includes an introductory zero-APR deal good for both purchases and balance transfers until May 2015, making it ideal for shifting your school shopping budget until later in the year. After that, the variable purchase APR ranges from 12.9 percent to 22.9 percent, based on your creditworthiness. This APR will vary with the market based on the Prime Rate. For each balance transferred there is a 3 percent balance transfer fee. Plus, Quicksilver's Visa Signature perks include discounts at online retailers and an extended warranty program.

Like all cash-back credit cards, you'll get the most from Quicksilver when you don't plan to carry a monthly balance. However, an excellent credit score can qualify you for an APR that's competitive among this card's peers. Still, if you're looking to convert your school shopping budget into a quick bonus, this card's got the summer's best deal so far.
