More questions

How much more does the 100 ml cost than the 50 ml?

A median $75 more at list price, for twice the perfume. The middle half of fragrances save between 25% and 33% per ml.

When is the bigger bottle not worth it?

When you have not worn the scent for a few days yet, or will not use most of it: the saving per ml only counts for perfume you use. Try a sample or travel size first; each fragrance page lists ways to try it.

How do I compare two sizes myself?

Divide the price by the milliliters on the box (3.4 oz is 100 ml, 1.7 oz is 50 ml). Our price per ml calculator does it for two bottles at once.
