Ok so Walgreens and CVS both have Cover Girl buy one, get one 50% off. So how would I use that with the BOGO foundation/lip gloss coupon? I'm thinking the best deal would be to buy two foundations, one full price and one half price, and get two lip glosses free. Because if you bought one & one then your 50% off discount wouldn't matter, right? Dunno why this is hard for my brain today.
