Bests & Worsts Reviews from Amazon

I bought this for my wife for Christmas, which she loved. Recently, she bought a travel size through Clinique directly and noticed the scents are different. She contacted Clinique through their website asking " How to spot imitations on the bottle and/or packaging". They did not answer her question but provided a more general response- "Thank you for taking the time to contact Clinique. We would like to explain that our products are distributed for sale only at our authorized retail store accounts (including certain direct TV sales), free-standing stores, and e-commerce sites. Products sold to our authorized accounts are genuine Clinique. Amazon is not one of our accounts and we have no control over the merchandise that they sell. Further, we have no way of knowing how they obtained our products. In this circumstance, we are unable to assume responsibility for unauthorized representation of our product. Once again, thank you for taking the time to contact Clinique. I appreciate the opportunity to respond to your concerns. You are valued as our consumer, and we hope you will continue to use and enjoy our products with confidence and satisfaction." Since we do not know if this was an imitation or old stock (as some reviews as suggested), In the future I will not be buying any perfumes from Amazon.
