So...one of the best apps I have used is Instacart.com. If you havent used it, it's a must! I just used it this passed weekend. They service major cities, Atlanta being one of them. It's an app that will deliver your groceries within 1 hour if you need it. They currently have Publix, Kroger, Whole Foods, Costco (no membership required) and Petco. First delivery is free for any or all of the stores. There is a minimum of $10 per store. I literally got one bottle of dish washing liquid from Costco and something from every store (well not Petco) delivered to my doorstep. After the first delivery, it's $3 per store for 2 hour delivery and $5 per store for 1 hour delivery. You can also schedule a time in the future if you are that organized. You can even say "Ok Google" to add items to your cart!
