Every morning: your shelf price and your competitors, in every chain
Cá Buồm reads prices every night in 11 Vietnamese retailers — Thế Giới Di Động, Điện Máy Xanh, FPT Shop, CellphoneS, Phong Vũ, Điện Máy Chợ Lớn, GearVN, MemoryZone, Co.opmart, WinMart, Kingfoodmart. Brands and distributors get a weekly report, price alerts and an API instead of a person with a spreadsheet.
What you get
Weekly report
Excel/PDF every Monday: your SKUs and competitors, price per chain, week-over-week change, promotions, minimum-price breaches.
Price alerts
Email or Zalo the same morning a chain drops below your floor or a competitor starts a promotion.
History
Daily price history per product per chain — for negotiations, for head office, for planning promotions.
API
JSON for your BI: best price, price per chain, history. Same data the site runs on.
Live sample report
Real numbers from tonight's crawl. Pick a category — the table is built the same way a client report is.
Prices per calendar month, VAT not included. First month free for the first five clients in exchange for a reference.
Request a demo report for your products
Send 5–10 product names or SKUs and the chains you care about. Within two working days you get a real report for them, free.
For advertisers
Reach people at the moment they compare prices
Cá Buồm compares prices of electronics and groceries across Vietnamese shops. Visitors come with one intent: to buy, and to buy where it is cheaper. Your banner or product sits next to that decision.
