Costco Tools by RestockBotAlerts 作成者: Tremscol

Costco precious metals sell out in minutes. By the time you hear about a drop, it is usually gone.

Costco Tools puts the drop, the math and the buy button in one place.

WHAT CAME BACK IN STOCK

A running list of the precious metals that returned to costco.com in the last 24 hours, newest first. The toolbar badge counts them, so a drop is visible without opening anything.

You decide what counts as worth knowing about: every metal, or only the items you are actually waiting for.

EVERY ACCOUNT AT ONCE

If you keep more than one Costco account in Firefox containers, one restock opens in all of them at the same moment. No signing out of one account and into the next while the listing empties.

The extension asks before it touches your containers, and you choose which ones take part.

IS THE PRICE ANY GOOD

Every product page gets the live spot price, Costco's premium over spot, and where that premium sits against its own recent history. A 2% premium means nothing on its own. It means something next to last month's.

WHAT YOU STAND TO MAKE

Each buyer row shows what that buyer pays and your estimated profit, worked out with your own cashback rate. Gains and losses are coloured, so the row reads at a glance instead of on a calculator.

HOW MANY YOU CAN STILL BUY

Costco caps units per day. The panel shows how many you have left against that cap, counted from your own order history, so you find out before checkout rather than during it.

CART AND CHECKOUT

Add a quantity from a product page or straight from a category grid, and it hands you to Costco's own checkout. It never places the order. You do.

If you keep cards in the vault, the checkout panel finds the right one fast: filter by Visa, Mastercard or Other, search by nickname or last four digits, sort A to Z, or show only the cards with a credit line above an amount you type. Each card's saved limit sits beside its nickname. Cards are encrypted on your own computer and never leave it.

YOUR ORDERS, IN YOUR DASHBOARD

Send your precious-metal orders to your RestockBotAlerts dashboard in one action, instead of copying them out by hand.

There is more: wish-list saving, a tab preference, folding panels, and a vault that locks itself.
