Ulta eye shadow quad ($12), you get one quad (the same or different colors) free. Use either the code for 20% off or $3.50 off (code: 49499), which ever one is greater (depends on your total purchase). Plus, if you shop through ShopAtHome, you will get 8% back, which almost covers the sales tax in Texas. Don't forget your 3 free samples. I recommend the Smashbox Photo Finish Primer. Also, sign up for the Ulta rewards card so you can rack up points to get future discounts! You will have to pay shipping, which is always $5.95, unless you purchase at least $50, not including tax.
Another awesome deal at Ulta right now is the "Cargo's Most Wanted Kit". It is selling for $15, but it is a $50 value. This could be a great Christmas gift or stocking stuffer. Unfortunately, you cannot use the coupon on this item, but you can still get the 8% back from ShopAtHome.
