I am all about getting the most beauty bang for my buck. That's why I stalk ULTA beauty ads looking for deals too good to pass up. For me a deal that's truly irresistible has to meet certain requirements. The product needs to be something I would normally buy, not just an impulse purchase that looks fun in the store buy looks like a stupid purchase once I get it home. There are so many high quality beauty products offered by drugstore brands I don't spend money on expensive prestige brands or beauty fads.
The bigger the discount the better. Right now ULTA has a Buy 1 get 1 at 50% off on popular skincare brands like Aveeno, ROC, Nivea, and Neutrogena. To get a great deal I always apply an ULTA coupon to the sale items I am buying. You can get coupons by signing up for the ULTA mailing list or printing coupons off their web site.
The only thing better than getting something cheap is getting something free! ULTA is giving away FREE quilted cosmetic bag with any $15 Roc or Aveeno skincare purchase. This deal hits all my sweet spots. It's a product I will actually use, the 50% off is a good size discount, I can use a coupon to shave a few bucks off my purchase, and as an added bonus I get a chic cosmetics bag for free! The only problem with a deal this sweet is selecting which bargain beauty products to buy out of all the many options.
