Per Piece - Unit Price Calculator per 100g, 100ml or Piece

Is the bundle actually cheaper? Per Piece shows the unit price - the real cost per 100g, per 100ml or per piece - under every price on the shopping sites you already use. It puts a small badge under every price showing what the item really costs per 100g, per 100ml, or per piece. The cheapest option on the page gets a green tick. Anything that costs at least half again as much per unit gets flagged in red. So a 300g pack at P62 shows P20.70/100g, and the "3PCS BUNDLE SALE" beside it that works out to P31.10/100g stops looking like a deal. WHERE IT WORKS Automatically on the large international retailers, Amazon among them, and on Shopee and Lazada across the markets they operate in. Chrome shows you the full list on the permissions screen before you install. On any other shop, open the popup and press Scan this page. The extension then runs on that one tab, only because you asked it to. Prices are read in whatever currency the page uses, and both number formats are handled, so 1.234,56 and 1,234.56 are never confused. WHAT IT DOES - Price per 100g, per 100ml, or per piece, right under the price - Marks the best value on the page, and flags the ones that are much worse - Reads multipacks properly: "300g x 6", "24 x 22g", "Twin Pack", "Pack of 42" - Reads shelf shorthand like "10s" for a 10-tablet pack and "30 Count" - Ignores struck-out original prices and uses what you would actually pay - Works while you scroll, on search results and on product pages WHEN IT STAYS QUIET A wrong number is worse than no number, so it shows nothing when it cannot be sure. Phones and laptops have no package size. A "30L backpack" is a bag, not 30 litres of anything. A listing holding two different sizes gives no way to tell which one the price covers. In all of those cases the badge is simply left off. PRIVACY There is no account, no sign-up, no API key and no AI. The extension never makes a network request on its own. Nothing is sent anywhere, and no data leaves your computer. All it stores is whether you switched the badges on or off. If a price looks wrong you can press the report button in the popup. It builds a note from what the page already showed you, copies it to your clipboard, and opens a pre-filled form so you can read it and decide whether to send it. Nothing is gathered in the background and nothing is ever sent by itself. Free, and open source. Not affiliated with, endorsed by, or connected to any of the retailers named above. The badges are a shopping aid based on the size stated in each listing. If a seller writes the wrong size in their title, the figure will be wrong too.
