About Costco Tools by RestockBotAlerts
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.
IT OPENS THE DROP FOR YOU
Turn on auto-open and a matching restock opens its own product page by itself. No click, no tab hunting, no needing to be at your desk at the right second.
Quiet hours stop it opening pages overnight. If several land at once it collapses them instead of burying you in tabs, and it can close the ones you never looked at.
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 colored, 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.
