How we pick Today's Top 20

The Top 20 is not the 20 biggest percentages. Each deal gets one score from real signals, and the list is rebuilt every hour when prices are re-checked.

What counts (current weights)

30% Genuine savings & price history: the store's own was price after our fake-"was" checks; the discount counts up to 60% and no further, and less when the price was not re-checked lately or never moved. Once we have 2+ days of our own checks, today's price against the earlier ones counts too.
20% Product relevance & shopper interest: everyday departments (electronics, home & kitchen, toys, clothing & shoes, household, beauty, gifts), prices under $25, $50 and $100, stores based in your country, and the store's own reviews when it shows them.
15% Price freshness & verification: how recently we read the price at the store, and whether the product link answered when we checked it.
15% Retailer reliability & availability: whether we re-read the store's whole catalogue lately, and whether the store marks a suspicious share of its items 70%+ off.
10% Customer engagement (real clicks & saves): real "Get Deal" taps and saves from SaleLark visitors in the last 7 days, used only once there are enough of them to mean something.
10% Total purchase value (incl. verified shipping): the money you save. Shipping costs are not known for these stores, so they are not counted.

When a signal is missing (no price history yet, no clicks yet, no shipping cost) we leave it out and share its weight among the signals we do have. We never fill in a number.

What never gets in

Price glitches and anything over 85% off (they have their own Glitches page).
Used, refurbished, open-box, commercial or industrial equipment, and items over about US$1,500.
Deals from stores that do not say they sell to your country.
Deals whose store link was broken, sold out or gone when we checked it, and prices not re-checked in 48 hours.

Variety

At most 3 deals from one store and 4 from one department while enough others qualify; never the same product or another colour of it twice. A deal that was in the Top 20 on each of the last two days steps aside unless it is still one of the very best. If fewer than 20 deals pass, we show fewer.

A sponsored deal is always labelled “Sponsored” and has to pass the same price checks. Affiliate commission is never part of the score.
