View PricingWhat is BuyLens?
BuyLens is a smart shopping comparison tool that scans the public web to find real product listings across major retailers and resale marketplaces. Instead of manually checking multiple sites, BuyLens does the work for you—showing prices, shipping costs, conditions, and explaining the tradeoffs between options.
Whether you're looking for the cheapest price, the best value, or the fastest shipping, BuyLens ranks options based on your preferences and shows you exactly why each result appears where it does.
We scan both retail sites (Best Buy, Walmart, Target) and resale marketplaces (eBay, Grailed, Poshmark, Depop, StockX, GOAT) to give you the complete picture. All from one search.

Does BuyLens store my data or scrape pages?
No. BuyLens only extracts structured product data (prices, titles, shipping) from public pages. We never store raw HTML and we always respect robots.txt.
Why do some sources show 'blocked' or 'captcha' status?
Some websites use bot detection. When we detect this, we stop immediately and record the status. We never attempt to bypass security measures.
How is total price calculated?
When shipping info is available and you have 'Include shipping' enabled, we add item price + shipping to get the total. If shipping is unknown, we show the item price only and note that shipping is unknown.

Ranking depends on your optimization choice. 'Cheapest' sorts by total price. 'Best value' considers data confidence and price. We always show what method was used.
