How we price a set

Every item in a set is priced at its full size's price per ml on Amazon today, from Amazon.com or the brand, and the items are added up. Sizes are the listing's; where a listing gives none, they come from Amazon's own per-ounce price for the set, and the set says so. Only sets whose every item we can price this way are here, which is why the list is short.

Questions

Are beauty gift sets cheaper than buying the products separately?

Of the 9 sets we priced, 5 cost less, 3 cost the same, 1 costs more per ounce. The biggest saving is 26%, on the Sunday Riley Power Couple Kit. Moroccanoil Hydrating Shampoo and Conditioner Set, 8.5 fl oz; Pureology Hydrate Shampoo & Conditioner Set, 9 fl oz; Pureology Strength Cure Shampoo & Conditioner Set, 9 fl oz cost what the full sizes cost apiece. Paula's Choice 8% AHA Gel & 2% BHA Liquid Travel Duo costs more per ounce than the full sizes.

How is a set priced against its full sizes?

Each item at its full size's price per ml on Amazon today: 50 ml from a 101 ml bottle that sells for $45 counts as $22.28. The set wins if it costs less than the items added up that way.
