New York…It is no longer a secret that kosher food prices have been rising but retailers say that customers are increasingly complaining about the spike. While many consumers seem to realize that higher fuel and transportation costs as well as sharply higher commodity prices are causing the increase, they want to make sure that pricing does not go beyond those costs that are passed on to grocers. Higher prices have also raised concern in Israel. According to Globes, as Strauss, Diplomat and other major suppliers mull raising prices, Israel's supermarket chains have joined the fray by urging consumers to rebel. The supermarket chains, who are calling on consumers to launch a "shelf products boycott" and not purchase products that rise in price have notified manufacturers and distributors who hike prices that they expect price cuts as soon as global conditions reverse the surge in raw materials and shipping costs.Rami Levy of the Rami Levy Chain Stores has called on consumers to rebel. "They're putting the cart before the horse. We haven't received new price lists, not even from Strauss, which mainly referred to coffee prices in its report. But, if there are price rises, the consumer is the one with influence. I call on consumers to go out on a new protest, a 'shelf products boycott'… it could be the next social protest."
