We just returned from a long vacation. In addition to the packing, traveling, flying, driving, laundry and fun we also have to eat! So before we returned from our trip I got on line with my grocery list (including meals planned for the week we returned) and ordered all my groceries. I order from www.safeway.com (it's the only delivery service around here). I had the groceries delivered the day we returned, but before we got home. It's great! The delivery service gives a one-hour window of when they will be delivering and I had our house sitter put the groceries away.
