Store Settings: Store Status
Use the Store Status panel in the Settings > Store Settings section to temporarily suspend your store. You can also enter a message that will be displayed to any customers that attempt to visit your store. Please note that this will not effect your subscription in any way. If at all possible, we recommend that you instead leave your store open and insert a note into the Welcome Message on your Home page stating that orders will not be dealt with until a certain date. Using that method, you will still be able to take orders while you're away, and it will still allow search engines to continue to index the pages of your store.
