Is ignorance bliss when it comes to sourcing? A recent poll of buyers in the retail, grocery and restaurant chain industries found that 75 percent of those not using e-sourcing methods are confident that they're getting the best value from their suppliers. But they're wrong, according to a report from Intesource. A suppliers' true rock-bottom price is almost always far lower than a buyer suspects. And it's even more likely another qualified source may be hungrier for new business. Buyers just need to know how to shift the tables.
