(CNN) – Amazon is cutting prices on hundreds of products at Whole Foods for third time since it bought the grocery chain two years ago.

The cuts go into effect tomorrow.

Amazon and Whole Foods expect customers to save an average of 20% on select items — including greens, tomatoes, and fruits.

The company will also double the number of weekly deals for prime members — and give them another 10% off hundreds of sale items throughout the store.
