I feel this is the absolute best way to sample all of your favorite perfumes without having to buy a full bottle. I do like how quite a few brands are making the rollerballs, those are usually one once and much smaller and less expensive that the full size bottles. I still prefer the samplers because I like collecting them. I must admit that I have them everywhere, in my purse, my car, my gym bag and in a few drawers around the house... just never know when I need a little fragrance pick me up throughout my day!
