We Search 8+ Retailers in Real Time
When you search, we query Amazon, Walmart, Target, Costco, and other major US retailers live. No stale data — prices update with every search.

We Calculate True Unit Price
We divide total cost by quantity (items, ounces, rolls, etc.) so you can compare apples to apples. Example: a 12-pack at $24 ($2/unit) beats a 6-pack at $14 ($2.33/unit) — even though it costs more upfront. But larger does not always imply best value.

We Find Best Value, Not Just Cheapest
Best value considers relevance, unit price, customer ratings, and review count. A product with 4.8★ from 50,000 reviews at $0.30/oz beats a 4.2★ product at $0.28/oz.

Affiliate Disclosure
Shopperoo earns commissions through purchase links. This keeps comparisons free but does not influence rankings.
