Best value, by cost per ounce
Ranked inside each category rather than across all of them. A gallon of drain treatment at twenty cents an ounce and a pet spray at forty-two cents are not competitors, and a single combined list would just sort by format.
One caveat that matters. Concentrates look expensive on this measure and frequently are not, because you dilute them before use. Until we have confirmed dilution ratios off the labels, treat concentrate rows as unresolved rather than as losers.

How this is calculated, and where it is weak. Price divided by volume in fluid ounces. Volumes were read from product titles by a parser and roughly half have not yet been checked by a human, so an individual row can be wrong. Weight-based products such as powders are excluded entirely rather than mixed in, because ounces of weight and ounces of volume are different units.
