Convenience stores earned their name by stocking food and everyday items in a shop you could easily reach. But what if your local store isn't all that close, or it doesn't carry what you're looking for? If everything goes according to plan, 7-Eleven might have you covered. It's testing a mobile app, 7-ElevenNow, that lets you order food, drinks and other products for delivery or in-store pickup. You won't have to brave the rain just to score a pack of your favorite soft drinks -- instead, a courier can bring them to you. The trial is active in 10 Dallas-area stores.
