Smashbox has a promo on Tuesdays and Thursdays called "Let's Do Lunch" where you get a free product with your order, in addition to the samples and FREE shipping you get any time you order from them.
There are no codes required, the product will automatically be added to your cart when you place an order between 9am - 2pm (PST). I usually order something from the Curtain Call category for around $10-12 to get my freebie. Last week I got everything in the picture about for $10 shipped! To make the deal even sweeter, I paid with my Paypal debit card using money in my account earned by completing surveys!
