Nothing unsettles the average Seattleite quite like the thought of change at the local grocery store. But change is almost certainly coming for many Seattle-area grocery stores if a proposed merger between the nation’s two largest supermarket chains — Kroger, which owns QFC and Fred Meyer, and Albertsons, which owns Safeway — goes forward. The deal, announced Friday, is causing a major stir in and around Seattle, where more than half of all households do most of their shopping at one of those four chains.
