Several stores launched grocery delivery services today in St. Louis, including Schnucks.

You order from Instacart online, then the food is delivered to your door.

You must be home to get the delivery, and there's a delivery charge depending on how much you buy.

Other stores launching the service include Straub's, Shop 'n Save, Whole Foods, PetCo, and Costco.

So many people took advantage of the new grocery service earlier today, Instacart temporarily put deliveries on hold.

Company reps say they had to bring in more personal shoppers to help with the volume. And while some of their delivery windows are sold out, you can still place orders.
