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.

DOWN TO THE LAST FEW? IT STILL GETS YOU IN

New in this version. When Costco has fewer left than you asked for, the add used to just fail with a useless error. Now the add-on tells you exactly how many remain, greys out the quantities that will not go through, and — if you let it — grabs what is left and takes you straight to checkout before it sells out. (Gold plan.)

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 pay. The toolbar carries a count of what you have not seen yet.

ONE CLICK, EVERY ACCOUNT YOU HAVE

Only Firefox can do this. If you keep several Costco accounts in container tabs, one click on a restock opens that product in every one at once — a tab per account, all loaded, while everyone else signs in and out of a single account. Every page and wish list it opens lands in the account you are already browsing, so you never buy from the wrong one.

IS THE PRICE ANY GOOD?

Every product page gains a panel with the live spot price, how far over spot Costco is asking, what the item has cost before, and what real buyers pay for it — so 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. Costco caps how much you can buy per day and per address; the add-on tracks both, so you find out now, not at the checkout screen.

YOUR CARD, READY, 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 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 — the whole position in one place.

There is more: save to your Costco wish lists, choose whether pages open in a new tab, and fold away panel sections you do not use.

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