How it works
-
1
Collect
A crawler checks every retailer's product page nightly and records price and stock status.
-
2
Normalize
Item price plus shipping becomes delivered price; package weight times potency becomes pounds of available chlorine.
-
3
Rank
Delivered price divided by pounds of available chlorine gives one honest, comparable number.
