Comparing seller reviews
How to compare reviews of perfume websites
Compare perfume-website reviews by recurring service themes and the exact products discussed, rather than star averages alone. Reviews can inform a purchase but cannot authenticate the particular bottle you will receive.
A HUME Fragrance buying guide

Separate service and preference
Order accuracy, communication and issue resolution are different evidence from a reviewer's enjoyment of the scent.
Check context across sources
Read experiences over time and from more than one source. One enthusiastic or angry account cannot describe every order.
Compare with current terms
A review may describe an old offer or policy. Use the live listing and published purchase information for the order you intend to make.
Try this before you buy
Summarize repeated service themes separately from scent opinions before comparing two websites.
