ACIE

Every offer, ranked on the evidence

ACIE compares live marketplace offers for the same product and ranks them on total cost, availability, delivery time and how recently each price was observed. Every position comes with the factors that produced it, and you can open the evidence behind any recommendation.

Total cost, not sticker price

Shipping is part of the price you pay, so it is part of the price we rank.

Every position explained

Open “Why this position” on any offer to see the exact factors that placed it there.

Commission never ranks

We earn a commission when you buy through our links. It does not touch the ordering.

From a search to a purchase you can defend

  1. Search a product, brand or model across every source we index.
  2. Resolve: listings that share a verified identifier are treated as one product, so you compare offers for the same thing, not lookalikes.
  3. Rank the offers on the factors below and read the evidence behind each position.
  4. Compare up to four products side by side on the same facts.
  5. Buy at the merchant you choose; ACIE hands you over and discloses its commission.

What decides an offer’s position

These are the weights the ranker applies today. They are the same for every merchant, and they are printed with every recommendation.

Total cost 40%
price plus shipping, lower is better
Seller trust 20%
seller rating where the marketplace publishes one
Availability 15%
in stock beats limited beats pre-order
Delivery time 10%
the merchant’s estimated days to deliver
Price freshness 10%
how recently the price was confirmed
Returns 5%
the length of the return window

An offer is only ranked when its price was confirmed within the last 72 hours and the listing matches the product with at least 60% confidence. Anything that fails those tests is listed as excluded, with the reason.
