If you don't have a ton of time or hate grocery shopping, try doing it online (Peapod is surprisingly affordable). This is a great way to avoid the tempting aromas and strategically placed impulse items and just shop for what you need. Best of all, you can save your grocery lists on the site, so if you buy the same stuff every week, your shopping can be done in literally minutes.
With just a little bit of planning, you can easily get into a groove of grocery shopping for just you—and save some money and waste less food, too.
