ok I think there are two sides, sampling is kinda very addicting...collecting all the cute little jars and slathering all the different colors on your face, and even if the foundation matches, you are determined to find the perfect match, or eyeshadow color, or anything. But I do think that if you are happy enough to buy full sized products, you will. I have yet to buy a full size, but I have ordered alot of extras and things, like lip glosses and such, so I don't feel like I am taking advantage, I really want to try what is best for my skin without spending money on something I will not use!
