Direct answer
How can I compare designer fragrance prices at LuxuryPricing?
Start with the fragrance collection or a house page, then compare the USD price shown on each product page. Add the bottles you want to a bag to see one subtotal before copying an order request.

Compare like with like
Use a house page when you want to compare products from one maker. Use the full fragrance collection when you want to compare across houses.
The product page is the source for the listed price. The bag is useful for checking the combined subtotal of several choices.
What this comparison does not claim
The catalog shows LuxuryPricing's own listed prices. It does not claim that a price is the lowest on the internet or copy a price from another seller.
