Right now Sephora is selling the Tarte EmphasEYES Waterproof Clay Shadow Sticks for $8, regular retail value is $25 each. That's a 68% savings. I love putting down a base color before putting on any eye shadows, it makes them really pop.
The colors available are Champagne(a shimmery beige), Moss Green(a dark olive green), Moca Berry(a dark reddened brown), and Charcoal(a sparkly dark grey). The Shadow Sticks are very pigmented and opaque, I highly recommend picking up these while they are still on sale.
