PerUnitPrice
Compare prices per unit, not per box
Price comparison tool that ranks new and used listings from eBay by price per unit of capacity, updated several times daily across 13 product categories.
Overview
PerUnitPrice is an independent price comparison site that shows eBay listings ranked by price per unit of actual capacity rather than total price. Instead of showing the cheapest box, it displays price per terabyte, per gigabyte, per core, per watt or per watt-hour depending on the product category.
The site covers 13 categories including hard drives, SSDs, memory, graphics cards, server CPUs, servers, 10GbE networking gear, LiFePO4 batteries, power stations, tool batteries, e-bike batteries, solar panels and 3D filament. All data comes from eBay US Buy It Now listings and is automatically refreshed several times daily.
PerUnitPrice filters out likely counterfeits, fake capacities, mislabeled items and suspiciously underpriced listings to keep tables useful. It also removes parts, accessories and repair items, and separates category-specific variants like server-only SAS drives into separate tabs.

Frequently looked up
- Q1Where do the prices come from?
- Prices come from eBay US Buy It Now listings accessed through eBay's official API. Only items located in the United States that ship within the US are included.
- Q2Is shipping included in the price per unit?
- Yes, when the listing states a shipping cost. When shipping is not stated (freight, calculated or pickup-only), the row is marked with '+ ship' and the price per unit uses the item price alone without shipping.
- Q3Can a seller pay to be listed higher?
- No. Every table is sorted only by price per unit, and nobody can pay to be placed higher in the rankings.
- Q4What listings are filtered out?
- PerUnitPrice removes listings for parts or repair items, accessories sold without the product, listings with operating systems preinstalled, mixed lots, and offers suspiciously far below comparable listings. For hard drives, server-only SAS drives are kept in a separate tab, and host-managed SMR drives and drives pulled from storage arrays are excluded from the main table.
