It says in their questions and answers that after signing up you can email them and list DVD's you don't want to receive. I don't know if you can add DVD's to the list from their catalog to the jewelry university set. It would be cool if you could get a check list or something to be able to click and choose your own DVD's to get each month while you're subscribed to it. I get why they cant send you DVD's in a particular order, it depends on what DVD's they have in stock from the university course at the time for your next DVD's to come to you.
For those that sign up if they have a place to say who recommended you please check me in there my user name there is
dbuckles@gmail.com it would be cool to be able to get a discount or something to sign up if I just brought them a few new customers.
