Costco Tools by RestockBotAlerts by 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 JUST CAME BACK IN STOCK

Open the add-on and see everything that restocked in the last 24 hours: the item, the price, how far over spot it is, and what buyers are paying for it. The toolbar carries a count of what you have not looked at yet.

ONE CLICK, EVERY ACCOUNT YOU HAVE

This is the part only Firefox can do. If you keep several Costco accounts signed in using container tabs, one click on a restock opens that product in every one of them at once — a tab per account, all loaded, while everyone else is still signing in and out of a single account watching the stock go.

Every page and wish list the add-on opens lands in the account you are already browsing in, so you never buy from the wrong one by accident.

IS THIS PRICE ACTUALLY ANY GOOD?

Every product page gains a panel with the live spot price, exactly how far over spot Costco is asking, and what that item has cost before. No more guessing whether 4% over is a bargain or a bad day.

WHAT YOU COULD SELL IT FOR

See what real buyers pay for that exact item, side by side. You know your spread before you buy, not after.

BUY IT BEFORE IT IS GONE

Pick a quantity and go straight to checkout in one click, running total in front of you. Costco caps how much you can order per day and per address — the add-on tracks both, so you find out now instead of at the checkout screen.

YOUR CARD, READY, AND NOT LYING AROUND

Save your cards encrypted behind a password only you know. They never leave your computer. At checkout one click puts the code on your clipboard, and clears it again shortly after.

WHAT YOU ACTUALLY OWN

Send your precious-metal orders to your RestockBotAlerts dashboard in one click, labelled by the Costco account they came from, and finally see the whole position in one place.

There is more where that came from: save to your Costco wish lists, choose whether pages open in a new tab or the current one, and fold away any part of the panel you do not use.

Costco Tools needs a RestockBotAlerts subscription, and the restock features need the Gold plan. It runs only on costco.com, inside your own logged-in account, and it never places an order — you always complete checkout yourself.
