While such a service does not provide anything you could not do for yourself, for someone like me it could save some time and effort by getting me organized on Sunday, as opposed to making an emergency trip to the grocer midweek. I don't know how many times I've stood in front of the refrigerator, hungry, and found nothing. Now that there some paleo cookbooks out, or coming out, maybe I can have a little more variety as well. Cookbooks also make weekly planning easier, but you do have to sit down and manually put together a shopping list.
Does anyone use this service or something similar, and what do you think about it? Are there any applications that would allow one to select recipes and automatically generate shopping/ingredient lists?
