Living in a rather remote area (40 miles to the nearest city) we do almost all our shopping online except for groceries and 1 or 2 trips year to Walmart. Online prices are often better than brick-and-mortar store prices, and even better with free shipping deals. So you save money, time & gas (which also equate to money), and don't even have to get dressed or put on lipstick.
Amazon is one of our favorites. Their grocery subscription program is really convenient and cost effective too. You receive a discount off the price plus free shipping.
