There is a sale running on Benefit Cosmetics right now- up to 70% off. I am seeing a few deals but Benefit products tend to be a little more expensive so even at 50% off the eyeshadow is $9.00.
If you spend $25 you will get free shipping plus you can use coupon code: SOPRETTY at checkout for a free package of post it notes.
You can head over to Amazon to see the sale items here. Note there are two pages of products.
