Chanel holds its marketing and retail in a death vice, and you will almost never see its fragrances on sale. In fact, I’ve noticed that some discounters actually charge more than the Chanel boutique or website!
There is one workaround, and that is when a large department store like Macy’s offers its several-times-a-year 15% off fragrances such as is going on right now.
You generally cannot buy these at Macy’s online but must walk into the store, and you can get 15% off on Chanel.
This is about the only time I purchase Chanel, and about the only time you will find it on sale at retail.
