Assuming lost sales at the retailers, we consider a one warehouse several retailers inventory system. Using the well-known METRIC-approximation as a framework, we present a heuristic for finding cost effective base-stock policies. In a numerical study we find that the cost of the policies suggested by the heuristic is on average 0.40% above the cost of the optimal (
