Raise for WalMart workers translates to only 1.1% increase in prices for walmart clients
"Even if Walmart were to pass 100 percent of the wage increase on to consumers, the average impact on a Walmart shopper would be quite small: 1.1 percent of prices, well below Walmart's estimated savings to consumers. This works out to $0.46 per shopping trip, or $12.49 per year, for the average consumer who spends approximately $1,187 per year at Walmart. This is the most extreme estimate, as portions of the raise could be absorbed through other mechanisms, including increased productivity or lower profit margins." page 3
