Ulta released a new coupon for $3.50 off any $10 purchase. There are a few of the "prestige" cosmetic collections that are excluded such as Bare Escentuals, Clarisonic, etc. But you can use this on sale and clearance merchandise as well. At my store, I can usually find some really nice salon shampoo on clearance and use the coupon to get it even cheaper, which is nice.
You can also use this online by entering code 61251 at checkout.
