CostcoInStock

Costco's gold bars, silver rounds, and platinum coins sell out within minutes. CostcoInStock watches them around the clock and notifies you the instant they're back — online or at a Costco warehouse near you.

PRECIOUS METALS

• Per-warehouse stock for nearby Costco locations, with addresses, distances, and low-stock flags
• Live spot prices for gold, silver, and platinum
• Over-spot premium next to every item — see at a glance which bars are closest to spot
• Filter by gold only, silver only, favorites, or in-stock-only
• History: last time each item was in stock and its last known online price

RESTOCK ALERTS

• Background refresh checks online and warehouse availability around the clock. Local notifications fire the moment something flips back to in-stock.
• No push server, no token — alerts stay on your device.

ANY COSTCO PRODUCT

• Paste any Costco URL to add a regular product to your list. Background refresh, warehouse availability, and restock alerts all work the same way.

PRIVACY

• No analytics, no tracking SDKs, no advertising IDs
• No backend server — your lists, status history, and settings live only on your device
• Uninstalling the app erases everything we store
• Costco sign-in happens inside an in-app browser; session cookies stay on your device
