CostcoInStock

Catch Costco's gold, silver, and platinum the moment they restock — with live spot prices, over-spot premiums, and per-warehouse availability.

Built for precious metals

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

Live spot prices for gold, silver, and platinum, refreshed continuously.
Over-spot premium shown next to every item — see at a glance which bars are closest to spot.
Per-warehouse stock for nearby Costco locations, with addresses, distances, and low-stock flags.
Filters for gold only, silver only, favorites, or in-stock-only.
Sticky history — last time each item was in stock and its last known price.

Works for any Costco product too

Beyond precious metals, paste any Costco URL to add a regular product to your list. Background refresh and local notifications work identically — no analytics, no ads, no servers.
