You can turn on and off vacation mode as you please. We highly recommend turning it on if you plan on being out of town or are unable to ship items for any reasons. If you do not turn vacation mode on and fail to ship an item within 5 working days of sale notification, the order will be cancelled and you will receive a 0-star rating which may discourage other buyers from buying your items in the future.
