Is Costco silver real?
Costco is the retailer. We scan the SKUs Costco lists — we do not assay or authenticate metal. Silver SKUs we have scanned include Sunshine Minting, PAMP Suisse, Perth Mint, and The Royal Mint.
What we track
- Sunshine Minting: bars and rounds we have scanned.
- PAMP Suisse: silver bars we have scanned.
- Perth Mint and The Royal Mint: coins and tubes we have scanned.
What we don't do
- We don't verify purity, assay cards, or mint marks ourselves.
- Weight, purity, and return rules are Costco's listing — not ours.
How does Costco's 1 oz silver premium compare to spot?

How do you buy silver from Costco?
Two inventories, not one. Costco.com is national checkout. Warehouses are a separate pile — the finder above lists which stores currently have an open in-store silver period. We never place an order for you. You check out with Costco.
- You need a Costco membership. Costco gates precious-metals checkout to members.
- Pick the channel. Online listings live at costco.com/precious-metals. In-store stock is warehouse-by-warehouse — not a backup of the website.
- If you are buying online, sign in on Costco.com. Then open the listing Costco is actually showing as in stock.
- Use the Costco.com median above for how long listings last. That figure is closed online windows in the last 30 days — not a stopwatch on every SKU.
- Our flip model uses Executive 2% plus a 2% card. Quantity, shipping, and return rules are on Costco's listing, not here.
What are the limits on buying Costco silver?
Costco sets purchase caps, shipping, and return rules on the listing itself. They have varied by item. Plan around the number on the page you are buying from — not around a figure on this site. We don't set Costco's rules.
Can you make money buying Costco silver?
Sometimes, on the model this page uses. Last week's best modeled flip is on the KPI strip (every confirmed period that week — Costco.com and warehouses). The rows below are closed Costco.com windows from the last 7 days.
Model: Executive Member cashback (2%) + a 2% card on the purchase + broker buy-back at 0.65% under spot. Spot-price risk during the hold period is not modeled.
Does the IRS know if you buy silver from Costco?
We don't file anything with the IRS for you, and we don't know what Costco files. Cash over $10,000 is a retailer reporting rule: Form 8300. Selling can have tax consequences. Ask a CPA.
General information, not tax advice. Consult a CPA familiar with bullion taxation in your jurisdiction.
Frequently asked questions
How the scans work, what Premium actually adds, and whether we ever buy the bar for you.
How fast are the alerts, really?
Hot Costco.com items are checked every 30-second scan cycle. A restock is confirmed after five consecutive matching scans at a 60-second confirmation interval by default. Then SMS, email, push, and Slack go out together. Warm, cool, and cold SKUs are scanned less often (2, 3, and 5 minutes).
Do I need Premium to see prices and stock?
No. Live prices, warehouse stock, alerts by email and push, National View, and profit math are on every account. SMS is the only Premium-gated capability — Silver Alerts Premium is $15/month after a 5-day trial.
Does this buy the bar for me?
No. We never place an order, hold a cart, or check out at Costco. The alert is the signal. You still need your own Costco membership.
Which brokers do you compare?
Four live bids: BGS, CollectPure, DCB, and Aligned Incentives. BGS, CollectPure, and DCB are polled about every 30 seconds; Aligned about every 60. Profit alerts skip a broker whose last successful fetch is older than 5 minutes.
How do I know an alert is real?
Confirmed restocks and stock-outs need five consecutive matching scans. Cancelled sessions that fell short stay visible on the dashboard with the mismatch that killed them.
Am I locked in?
No contract, no minimum term. Cancel any time; you keep Premium until the billing period ends.
