FinalPrice

See the real cost of anything — detects prices on any page and shows the tax-included total instantly.

The price tag says $24.99. Your card gets charged $27.11. FinalPrice closes that gap by adding sales tax to every price on the page, so you see the real total before you buy. WHAT IT DOES • Finds prices on any page and adds a small badge with the tax-included total • Replace mode swaps the original price for the real amount instead • Works on Amazon, Walmart, eBay, and any other shopping site • Handles Amazon's split price layout, dynamic pages, and prices that load as you scroll TAX RATES • Detects your US state automatically the first time it runs • Prefer manual? Choose a state from the dropdown or type an exact sales tax percentage • Stack a city or county rate on top of the state rate SMART DETECTION • Prices that already include tax (standard on EU and UK sites) are left alone • "Free shipping on orders over $35" gets no badge, since that's a threshold, not a price • Tax-exempt items, like groceries in some states, get a "tax-free" label instead SITE CONTROLS • Set a custom rate for a specific store • Change the badge text globally or per site • Block sites you don't want it on, or run it only on sites you choose CURRENCY CONVERSION • Shows foreign prices in your currency using live exchange rates • Rates refresh hourly PRIVACY • No data collection. No ads. • Settings stay in your browser • Network requests happen only for location detection and exchange rates • Full privacy policy linked in the extension
