Vons allows you to tip your driver, but only in certain regions and depending on the store where your order is coming from. In order to do so, proceed with your order to checkout, where you can select your payment method and then click submit. Once this has been processed, you may see a message that asks if you'd like to leave a tip. Other than this, you may wish to tip the driver in-person in cash. Tips will be refunded if the order is cancelled or returned, but will not be refunded for partial cancellations or refunds.
