Amazon today unveiled a preview of its official rewards program for Whole Foods shoppers by slashing prices on turkeys and other items ahead of the holidays, while offering even deeper discounts to customers who are also Amazon Prime members. Amazon’s plan to reward Prime members with additional savings was previously announced by the companies as one of the many integrations and perks following Amazon’s $13.7 billion acquisition of the grocery store chain this year.

Following the deal’s close, Amazon immediately made good on some of those promises by lowering prices on select grocery items.
