Wearing perfume or cologne is all about self-expression. Personal fragrances can change your mood, boost your confidence, or take you back to that special place that the scent reminds you of. Online shopping for perfumes can be tricky, but some websites out there do a great job making it easy, typically at a fraction of the in-store price. A concern in the perfume industry is scamming. Store ratings can help you decide if you're purchasing from a trustworthy online shop.
