I have never returned an item so far because I'm very careful about what I buy and I seldom regret buying something.. But this time I have to return my foundation and I'm kinda shy, what if they don't want to accept it.. I tried the foundation in the store and I loved it, the color matched, the look was perfect, so I bought and the next morning when I wanted to wear it, I noticed the terrible chemical smell that made me sick. I could never use it, the foundation is definitely bad (or rotten or which word I should use here?), I use other types of MAC foundations for ages, none of them has this smell.. I hope they can change it when I return it, because it has been 5 days since I bought it and it is impossible if they claim it is a "customer fault".. :l
