Paste anything

ASIN, UPC, retailer URL, or just the product name. The resolver auto-detects the type and starts the sweep.

No login · no card · no anti-bot wall

See every retailer that has it

We sweep 50,000+ stores in our catalog and show you who has it in stock, at what price, sorted lowest-first. In-stock-only is the default.

Walmart · Target · Costco · Home Depot · BAM · CVS · 49,994 more

Click through to the deal

Every link routes through our affiliate-disclosed redirect — you never see surprise tracking parameters, and we never overwrite anyone else's. The price is always the actual lowest, not the highest-paying.

03

04

Extension seller mode on every Amazon page

[ Trust ]

Cheapest first. Always.

We earn commission on some clicks — and we never let that change what ranks where. Three rules we wrote down so you can hold us to them. Full ranking rules →

01

Lowest price always wins #1

The cheapest in-stock offer is always the first row, period. Affiliate partners can win tiebreakers only within a 3% margin — position #1 is never re-ranked to favor commission. Read the full math on /how-we-rank.

02

We never hijack other affiliates

Honey, Rakuten, and Capital One Shopping rewrite affiliate tracking at checkout — meaning small publishers lose attribution on sales they earned. We don't. Our links only fire when you actually visit us first.

03

Sponsored rows are labeled

If a retailer pays us a commission on a click, the row carries a visible "Paid link" badge. Affiliate disclosure is in-view on every results page, not buried in the footer. FTC-compliant by design.
