Amazon officially owns Whole Foods, and promised to cut prices on day one.

Bloomberg did a little cost comparison and found prices are indeed lower on some items, compared to last week.

Organic Fuji Apples per pound are now 43-percent cheaper.

Whole Trade Bananas are 38-percent cheaper.

Responsibly farmed Salmon and Tilapia fell to 33-percent cheaper.

85-percent lean ground beef fell to 29-percent cheaper, as well as organic avocados.
