when i was getting studio fix fluid in nc42, they gave me select spf 15 (i think that's what the other glass bottle one is called.) THREE times. twice i got all the way home and had to go back, the third time i caught it in the store, and they realized they had accidently put the wrong foundation in the wrong box. it was their mistake, they (rightfully) fixed it. unfortunately, mistakes do happen, especially when you have so many similar looking products. hopefully, they'll be sweet about the exchange for you. more times than not, mac MAs have been wonderful to me.
