Competitor price tracker for Walmart Marketplace

If you sell on Walmart Marketplace in a competitive category, a rival's quiet price drop or stock-out can cost you sales before you ever notice. SpotRival watches your competitors' Walmart Marketplace product pages around the clock and alerts you the instant something changes.

How it works on Walmart Marketplace

Walmart Marketplace listings are supported on a best-effort basis, with resilient checks that avoid false alerts.

1. Open a competitor's Walmart Marketplace product page.
2. Click “Watch this page” in the SpotRival extension (or paste the URL into your dashboard).
3. Get an email + browser alert whenever the price changes or stock flips in/out.

What you can track

• Price changes — up or down, with the exact amount and percentage.
• Stock status — when a rival sells out (your chance to win the sale) or restocks.
• Price history — spot a competitor's discount patterns over time.
