I enjoy them, at least the kinds filled with make up and skincare! This program is so much fun, and now its even less expensive! Have you ever tried Test Tubes? New Beauty magazine sponsors this product. I've been 'subscribing' to Test Tubes on and off for the past 3 years or so. It gives you the opportunity to try products that you may otherwise be unfamiliar with, but you may find that you love. Some of the products are close to full size and last a couple of weeks.
I couldn't find on the site if the program is shipped outside of the US (sorry).
