To help you shop smarter, the Hearst Television Data Team has developed the Prime Day Deal Checker tool. This tool compares a product's price with its lowest price of the year and the last 30 days, then rates the deal as very good, good or not good.

Target, Wayfair, Nordstrom, Brooklinen and Saks Fifth Avenue are among the retailers offering up to 70 percent off clothing, accessories, furniture, decor and more.

The officially licensed fast-paced strategy game had already received an early Prime Day deal, but Amazon has slashed the price again.

Amazon extends Prime Day to four days and moves it up a week to get in front of tariffs. Walmart and Target plan competing sales events to capitalize on consumer worries.
