Dealophant — the real cost per unit on every Amazon product
Dealophant is a free price-per-unit comparison search engine for Amazon. It ranks listings by true cost per ounce, per fluid ounce, per roll, per pod, per bar, or per serving — pulling live data from the Amazon Product Advertising API on every search.

How it works
Each search picks one canonical unit family — weight (ounces), volume (fluid ounces), count (rolls, pods, bars), or servings — and ranks every in-stock Amazon listing in that family by computed price per unit. Cross-unit listings are shown separately under "Other formats" so the ranking stays apples-to-apples.
