Before you buy anything, check it.

Sift compares real offers across marketplaces and merchants the moment you ask — total price, delivery, seller quality, cashback — and tells you which one is actually worth taking.

How it works

  1. You ask

    Type a product, click “Check this page”, or highlight anything on any site and choose “Find Better Options”. Sift does nothing until you do.

  2. Sift checks

    Live offers are pulled from marketplace and merchant programs, then ranked by what they actually cost you: price plus shipping, delivery time, seller quality.

  3. You decide

    One clear comparison, one recommendation, and a View Deal button that takes you straight to the seller. Eligible purchases earn you cashback.

Built to be on your side

Ranked for you, not for commissions
Ranking is weighted 85% to your value — total cost, delivery, seller quality. A high-commission offer can’t outrank a genuinely better one, and sponsored placements live in their own labeled slot, never inside your results.
Only when you ask
No background tracking, no reading pages you didn’t act on, no browsing history collected. Every check starts with your click, and that’s the only time Sift looks at anything.
Honest links, always
View Deal takes you to the seller. If a partner link can’t be created, you still go straight to the deal — Sift never blocks or reroutes a purchase to protect its commission.
