We've long been fans of buying perfume "minis" for saving money as rarely does the "value size" of anything really offer any value, so seldomly do we use up monster-portions of beauty products before they've grown rancid or tiresome.  Not only do perfume minis give you the chance to test out a new scent without a lot of financial risk and the flexibility to move on to a new scent once you've outgrown the old, roller ball minis are perfect for travel or giving your scent a boost leaving work for a night on the town.
