I've been switching on and off between Arbonne and Mario Badescu skin care line. They are so great with samples! You can go to this link
http://www.mariobadescu.com/questionnaire.aspx fill out the questionnaire and in a few days they'll email you and ask you if you want to try samples. Before they email you though they'll give you a list of prodcuts that they recommend. Just ignore that and wait for the email.
They give big samples and I still have them after a month!
I even emailed them back and asked if I could try a different toner and I got it within a few days.
Check out their client list too!
