Amazon Prime members can now get 5% back at Whole Foods

The move is yet another benefit to being a Prime member and also aims to help undercut the "Whole Paycheck" view of the grocery chain. Now it looks like they might have come up with a way.

Amazon has found another way to leverage its acquisition of Whole Foods Market by giving the grocery store's customers an incentive to become members of its Prime program.

Discount retailer Target Corp already offers a REDcard credit card that gives shoppers 5 percent off purchases at its own stores.

From lowering prices on popular items and delivering everyday staples and locally sourced items through Prime Now to rewarding customers for shopping Whole Foods Market's quality products, the Amazon Rewards Credit Cards are another way both companies are working together to improve the lives of customers.

Amazon's Prime service offers two-day shipping plus video streaming and other perks for $99 a year or $12.99 per month in the United States. The card already earns 5% back on Amazon purchases as well as 2% back at restaurants, gas stations and drugstores, along with 1% back on everything else, making it a competitive card for budget-conscious consumers.

Expect to see more integration between Amazon's technology and Whole Foods. Amazon has said Prime is becoming the loyalty program for the chain which it acquired a year ago, although how exactly that would work remains unclear. Additionally, there is also a new Whole Foods online storefront on Amazon's websites. "There is little doubt that Amazon's approach to building a relationship with Whole Foods shoppers is based on value and rewards and will be hard for other grocery retailers to match", he wrote.

However, all has not gone well between the two companies.
