Maybe a more prudent approach is to change your grocery delivery app to one that has multiple stores. If you are using a service like "Peapod" that is tied to your local Stop & Shop, find another service that works with Food Universe, Key Food or CVS. We have too many choices in NYC, but further away, Wegmans is not running out of anything they can't replace in 3 days. We are not going to run out of bottled water.
Oh yeah - buy a Brita or a better filter. It solves this problem using plentiful tap water.
