Alert: The discontinued shades for Urban Decay's 24/7 Glide-On Eye Pencils are now discounted by 50%, from US$19.00 to $9.50, here on the brand's site.
Note that they did take down the free-shipping-on-$35 and deluxe-samples-on-$50 promotion that they were running just a few days before. However, they do still have stock of some of the good sale items that they had before, and also added Urban Defense. (I have two different shades of Urban Defense in the old packaging; I liked it, and would definitely recommend it over their BB cream.)
Also, if you need help moving on from the discontinuation of one of your favourite liners, see my list of (cheaper!) dupes here.
