Amazon Buy Box & FBA Undercut Sentinel

For Amazon FBA brand owners and third-party sellers, the Buy Box controls over 82% of all marketplace sales. If a competing seller undercuts your offer by even two cents, or quietly applies a 5% digital clipping coupon in the middle of the night, Amazon silently reallocates the Buy Box to them.

The worst part? Your automated Amazon PPC ads keep running and spending your daily budget—sending paid shopper traffic directly to a product listing where your competitor gets the sale.

The Amazon Buy Box Undercut Sentinel checks target ASIN product listings every two hours, detects price changes, coupon badges, and seller rotation, and alerts you the moment you lose ownership.

The Real Pain Point It Solves

• Burning PPC Ad Spend on Competitor Sales: Paying $1.50 per click on sponsored product ads while a competitor holds the Buy Box means you are literally paying to advertise your rival’s inventory.
• Stealth Digital Coupons: Traditional scrapers and simple repricers only read the base sticker price, completely missing Amazon “Clip Coupon” checkboxes (e.g. “Save an extra $3.00 at checkout”) that steal buyer preference.
• Delayed Repricing Reaction: Discovering a lost Buy Box 18 hours later after your daily revenue has cratered by $1,200.

1. Full Page DOM Render: Tishtar loads the Amazon product page using a clean cloud browser, extracting the current Buy Box winning seller name, base price, shipping speed, and any active clipping coupons.
2. True Effective Price Calculation: The engine computes the Effective Landed Price (Base Price - Coupon Value), revealing hidden discounts that standard repricers miss.
3. Instant Telegram & Webhook Dispatch: If the Buy Box ownership shifts away from your merchant storefront, Tishtar dispatches an immediate mobile notification with the exact price needed to win it back.
