Get 10% cash back with this credit card

Cash back credit cards are a great way to earn money on everyday purchases. While it's not unheard of for credit cards to offer cardholders 5% or even 6% cash back on items, it's nearly impossible to see cash-back offers in the double-digits. At least, until now.

American Express recently launched a limited time bonus for two of its cash back cards - Blue Cash Preferred from American Express and Blue Cash Everyday from American Express. Those who apply for either card by June 15, 2016 will earn an impressive 10% cash back at any US wireless telephone service provider, up to $200, in addition to the regular cash back perks each card offers. Cardholders can earn 10% cash back when buying a phone, accessories, or paying a bill at any wireless phone provider from now until December 31, 2016. The 10% back is issued as a statement credit on your card.

Which card is right for you?

Blue Cash Preferred from American Express users earn $150 cash back after spending $1,000 in the first three months of opening the card. By maxing out the 10% cash back at mobile phone service providers to the full $200, you're looking at a total of $350 in cash back earnings in upfront bonuses. Cardholders also earn an ongoing 6% cash back at supermarkets (on up to $6,000 in purchases annually, then 1% back), an unlimited 3% back at gas stations and select department stores like Macy's, Sears, and Nordstrom, and 1% cash back on all other purchases.

Rewards can be redeemed as a statement credit, merchandise, or gift cards. There's also a 12-month 0% intro APR on purchases and balance transfers, which can help you save money on interest fees for the first year.The card does have a $75 annual fee, but the average spender can more than make this back each year. That's part of the reason why Blue Cash Preferred comes out on top in NextAdvisor's cash back credit card analysis.

If you'd prefer a card with no annual fee, Blue Cash Everyday from American Express is a great alternative. It offers similar benefits to Blue Cash Preferred, but has no annual fee and lower cash back rates. In addition to the limited-time offer of 10% back at wireless phone providers, users will receive $100 cash back after spending $1,000 in the first three months. Combine that with the $200 cash back opportunity at mobile phone providers, and you can earn a total of $300 cash back in upfront bonuses.

Additionally you'll earn a standard ongoing 3% cash back at supermarkets (on up to $6,000 in purchases annually, then 1% back), an unlimited 2% back at gas stations and select department stores, and 1% back on everything else. Similar to Blue Cash Preferred, you can redeem your earned rewards for a statement credit, merchandise, or gift cards. The card also features 12-month 0% intro APR on purchases and balance transfers.

If you are interested in either of these cards, now is the time to get them. Keep in mind these limited offers are only open to those who apply by June 15, 2016, and the 10% back bonus at wireless providers is valid through the end of 2016.
