Quantity information for products on Amazon is mostly unavailable, leaving you to figure out unit prices. In order to get you useful unit prices for comparison, ByTheUnit does a few special things before it displays a neatly sorted list of results:
- Return accurate search results from Amazon, identifying if each item is prime-eligible.
- Run the results through our custom unit-price engine which interprets the item description to pull out quantity and units, making sure we account for the hundreds of different ways an item could be described.
- Use measurement conversions to normalize units for price comparisons, when possible.
