Amazon Prime Rewards Visa Signature Card

The Amazon Prime Rewards Visa Signature Card, issued through Chase, has some enticing rewards: 5 percent back on purchases you make on Amazon and at Whole Foods, as well as 2 percent back at restaurants, gas stations and qualifying drug stores, plus 1 percent on all other purchases. When you sign up, Amazon also throws in a $70 gift card bonus.

Users receive benefits from the Visa Signature Luxury Hotel Collection and some travel coverage, including a damage waiver on auto rentals.

There's no foreign transaction fee, so you're free to use it outside the U.S. without paying extra.

Be wary of carrying a balance since its APR is relatively high. And although the card technically doesn't have an annual fee, it is, as we mentioned, exclusive to those who pay for Prime membership, which now costs $119 per year.

The Prime Rewards card is the better option if you're spending more than $5,950 per year on Amazon and at Whole Foods. At that level of spending, the extra 2 percent back exceeds the Prime membership fee.

This card has a similar structure as the Prime Rewards card, except it only offers 3 percent back at Amazon.com and Whole Foods, not 5 percent, and a $50 gift card bonus rather than a $70 bonus.

Prime offers a number of other perks, though, including free two-day shipping on Amazon goods, Prime streaming benefits and free Whole Foods delivery in select cities, and many Amazon shoppers decide membership is worth the cost, with or without the credit card.

If you're not someone who shops at Amazon enough to justify the subscription to Prime, you'd probably benefit more from another credit card.

The Chase Freedom, for example, is CNBC Make It's No. 1 cash back card overall, since it offers 5 percent back on categories that rotate every quarter.

The Capital One Venture, meanwhile, our No. 1 travel card, offers 10 points on purchase at Hotels.com/Venture, plus a flat rate of 2 points back on all other purchases.

The Discover It Cashback Match offers 5 percent back on purchases at Amazon, but only during one quarter of 2018. As for the Whole Foods benefit, the Blue Cash Preferred has a competitive offer — 6 percent cash back on groceries year-round — but it also requires a $95 annual fee.

All things considered, if you're someone who shops a lot on Amazon and/or if Whole Foods is your go-to grocer, it's worth considering one of the Amazon Rewards cards — especially if you're a Prime member.
