Guides
Four questions, answered with the pairs on this site and the numbers behind them. Each list says how it was ranked, so you can disagree with the order.
The best beauty dupes under $20
Every pair here has a dupe that costs less than $20 and replaces a product costing at least twice that.
Skincare dupes that share the same active
A skincare dupe is only worth buying when the ingredient doing the work is the same one.
Makeup dupes that match the finish, not just the shade
Shade matching is the easy half.
The biggest savings on the site
The extremes: pairs where the cheaper product costs a tenth of the original or less.
