Consider whether the scent is one you reach for daily or only occasionally. Larger sizes are not always better if a perfume sits unused.

Spray and oil products can use very different applicators and usage amounts. Volume alone does not make them equivalent.

Read the finished product's specifications and price rather than estimating wear time from another brand.

Compare the complete product information before purchase and retain the order details. Good fragrance ownership begins with knowing what you have chosen. A careful choice is about suitability and enjoyment, not simply owning the largest bottle.
