How we rank offers

UnboxExpert orders products by a published score. No store can pay for a higher position; if a paid placement ever appears it will carry the label “Advertisement”.

The score

Each product gets one place, represented by its best combination of store and warehouse for your delivery country. Its score is:

score = 100 × Gate × Trust × Fresh × (0.30·D + 0.25·H + 0.15·Q + 0.15·A + 0.15·C)

Gate: 1 only when the store has an active partnership with us, the link works and the product is in stock for your country; otherwise the product is not listed.
Trust: how certain we are that the coupon or price works, from the store's own data and our checks.
Fresh: how recently we checked the offer; older checks count less.
D, real discount (30%): the final price against the median of the prices we recorded ourselves over the last 90 days. Until we hold 14 days of our own prices for a product, this part of its score is 0.
H, demand (25%): mentions of the product in independent sources, and clicks and code copies on UnboxExpert.
Q, quality (15%): buyer ratings, weighted by how many orders they come from.
A, availability (15%): how fast the product reaches your country, from a local or regional warehouse first; products that do not ship to you score 0.
C, commercial value (15% at most): what the store's partner programme pays us for a sale. Its weight never goes above 15%.

Discounts we show

A discount percentage is shown only against the lowest price we recorded ourselves over the previous 30 days. A coupon code's own value (for example "takes 8% off orders over US$1") is shown next to the code as the store's coupon terms state it. Every price shows when we last checked it; currency conversions are always approximate.
