It's great you can choose from some samples and trial sizes with online purchases so you can try products you're interested in to see if it works for you or not. Shipping has always been pretty good. Nevertheless, I continued to look for an alternative to this site to get my favorite tretinoin. So happy I found it, just google 'Topa2get' to find a website with a lot of products with cheaper prices. Amazing service! Ordered Friday & delivered at 11am Monday. Can't ask for better than that.
