This is the retailer with the best back-to-school deals by Michal Addady @FortuneMagazine September 2, 2015, 5:12 PM EDT E-mail Tweet Facebook Linkedin Share icons Profitero, a leading global provider of e-commerce intelligence, compared online back-to-school deals for three top retailers — Amazon, Walmart, and Target — to find out which one offers the best prices, Forbes reports. It examined almost 4,000 of the exact same products on each of the three websites. It checked the prices on August 18, around peak back-to-school purchase time, to get the most accurate information. Amazon had the best prices, but only beat out Walmart by 1%. 91% of the top selling office products were available for free shipping through Amazon Prime, so the deal was sweetened for members who pay a $99 annual fee for that service. Target lost by a landslide with prices that were 25% higher than Walmart’s.
