Whole Foods is selling turkeys to Amazon Prime members for 50 cents a pound cheaper than is available for other customers.

The deal is a "sneak preview" of what it will look like when Amazon Prime is Whole Foods' official rewards program.

Whole Foods also just announced a new round of price cuts for all shoppers.

Whole Foods Market just offered customers a revealing "sneak preview" of what its Amazon Prime Rewards program will look like.

On Wednesday, the grocery chain released a new list of price cuts. While turkey will now cost less for all Whole Foods customers, Amazon Prime members will receive an additional 20% off.

Starting Wednesday, organic turkey will cost $3.49 per pound, and traditional, non-antibiotic turkey will cost $2.49 per pound. Prime members will be able to buy turkey at $2.99 per pound and non-antibiotic turkey at $1.99 per pound.

According to a press release, this offer is a "sneak preview" of what it will be like when Prime becomes the official rewards program of Whole Foods.

"These are the latest new lower prices in our ongoing integration and innovation with Amazon, and we're just getting started," John Mackey, Whole Foods' co-founder and CEO, said in a statement. "In the few months we’ve been working together, our partnership has proven to be a great fit."

Shares of Kroger's fell up to 3.5% on Wednesday after the Prime discount and other price cuts were announced, Bloomberg reported.

Amazon's acquisition of Whole Foods has been a dicey scenario for other grocers, especially as e-commerce becomes increasingly important in the grocery business. Shares of Kroger, Target, Costco, and Walmart all plummeted after the news was announced, with Kroger's shares hitting a three-year low.

If you're a Prime member and want to cash in on the discount, go to Amazon.com/turkey and present the coupon from the webpage when you're checking out. If you're a Prime member and recently purchased a turkey from Whole Foods at full price, you can go back to the store where you made the purchase with your receipt and get a store credit.
