There are a couple of ways to request a quote for a list of titles. If you created a list online, click on My Account > My List. My lists will allow you to select from your Current List or Archived Lists. Then click the Order Now button.
Follow the order wizard and indicate in the Special Instructions section that you need the list quoted. It is also helpful to specify the time frame for which you need the quote and the method that you would like to receive it.
