Silver Alerts tracks live silver inventory at every US Costco warehouse and its online store — live map, zip-code search, months of stock history per store — and alerts you the moment stock is confirmed at your store or online. Four live buyback offers and your own cashback math show what each find is worth before you buy. No refreshing the Costco website, no calling stores.
Silver on the shelf at 197 of 657 Costcos · 31 sold out in the past 24 hours — see which ones inside.
Five tools that do the heavy lifting — in-store inventory, online tracking, payouts, profit math, and alerts by text. Every section below maps to a screen in the product.
Drop in your zip code to see what's in stock at a Costco near you — then let the alerts do the driving. Watch how inventory has moved across the entire US network — 30/60/90-day history overlaid against the silver spot price. You can also track how Costco silver inventory has moved week over week in our running price-and-restock report.
Every gold and silver SKU Costco lists, with the four largest precious-metal buyers' bids refreshing continuously. Best bid per product highlighted automatically. Each row expands to show your real payout after Venmo, Citi Plus, or VentureX cashback — no calculator required.
VentureX on one purchase, Citi Plus on the next, Venmo for the online order. Configure each card or payment method as its own profile — cashback %, Costco Executive bonus, additional cashback, shipping, sales tax — and toggle profiles on or off any time. The math reprices instantly across every screen.
Every way stock moves, covered: in-store restock alerts for the warehouses you pick, online restocks that re-arm after every sellout, brand-new SKUs the moment Costco lists them, spot-price targets, personalized profit thresholds, and automatic price anomalies near or below spot. Restock notifications arrive by SMS, email, or push — set a rule once and it shows its status, channels, and last-fired time.
Silver is near record highs and the best restocks sell out fast. SMS is the channel that keeps up. We bake the SKU, premium over spot, store distance, and a one-tap product link into every text, so you can move before anyone else has even opened their email.
Beyond the core five, these are the everyday tools — anomaly detection, spot-price alerts, the live event stream, and your portfolio.
Automatically flags Costco prices that approach or fall below spot — no user threshold required.
Get notified when gold or silver crosses your target threshold. Single-fire by design.
Track every Costco buy and broker sell. P&L, hold time, and cost-basis math all roll up automatically.
Every confirmed restock and stock-out across all warehouses as it happens — premium-over-spot tagged and time-stamped.
Three things we do that nobody else in this space does — and a head-to-head against the typical alternatives.
We scan the Costco website every 30 seconds — a third faster than the 45-second cadence common in this space. End-to-end alert latency typically lands under 60 seconds.
SMS is the channel for under-minute windows. Email and push fan out in parallel for everything else. Our Slack bot delivers the same alerts straight into your workspace — and our Slack community is where active buyers compare notes in real time.
When Costco lists a product close to or below spot, our system catches it automatically — no threshold setup required. This catches genuine pricing errors that competitor tools miss entirely.
Every confirmed alert is backed by 5 visible scans in your dashboard — and cancelled false detections stay visible with their exact mismatch count. Every notification carries a dispatch timestamp so you can audit channel-by-channel delivery in milliseconds, not "sometime last hour".

These are real Costco listings where rewards plus broker buyback pricing created immediate resale profit. ROI compares profit to the Costco purchase price; broker buyback assumes spot − 0.65%.
A few good buys at the right premium cover the cost of a full year. Add a credit-card signup bonus on the same buys, and the math goes from "pays for itself" to "pays for the next few years."
A few good buys. One signup bonus. The year is covered.
Silver Alerts Premium runs $15 / month. Set your cashback stack once and every silver product reprices to your real margin — a few good buys at the right premium cover the year, and an anomaly catch (a Costco listing near or below spot) can do it in one.
Our hot tier scans the online store every 30 seconds. The end-to-end path from an online inventory change to an SMS on your phone is typically under one minute, often closer to 30 seconds. We don't batch, queue overnight, or hold for digests — the second a five-scan confirmation passes, dispatch fires in parallel across every channel.
It's the same idea, minus the part people worry about: Silver Alerts is a monitoring and alert service that scans the Costco website every 30 seconds and checks every US warehouse throughout the day, then texts, emails, or pushes you the moment stock is confirmed. It never auto-purchases — no bot buys anything on your behalf. You get the alert; you buy from your own Costco account.
Speed and coverage. The best restocks sell out fast — often before a manual check would have caught them at all. We watch every US warehouse and the whole online catalog at once, confirm each event with 5 consecutive matching scans, and deliver it to your phone — no refreshing, no phone tree.
No — we alert, you decide. There is no auto-checkout, no stored Costco login, and no purchasing on your behalf.
No. Silver Alerts Premium comes with unlimited searches — the product does the searching for you anyway, since it scans the catalog continuously on a 30-second cadence.
Four live: BGS, CollectPure, DCB, and AlignedIncentives (labeled "Ali Incentive" in the UI). Each refreshes their bid table continuously; we pull on a ~30-second cadence and push to your dashboard in real time.
Every confirmed restock or stock-out is backed by 5 consecutive matching scans. Each scan in that sequence is visible in your dashboard, including the timestamp and matched fields. Cancelled false detections (sessions that fell short of 5 matches) are also surfaced with the exact mismatch count — so you can audit when the system second-guessed itself and why.
Once a confirmation passes, dispatch fires across SMS, email, and push in parallel within a sub-second window. Every alert in your history shows the millisecond-precise dispatch timestamp for each channel — no black box. Typical end-to-end latency from inventory drop to your phone is well under a minute.
Every text is brand-prefixed with [Silver Alerts], includes the SKU, store and distance, Costco price, current spot, premium percentage, and a one-tap link to the live product page. We respect quiet hours and per-alert 3-hour cooldowns.
Three things: (1) SMS as a first-class channel — on top of email, push, and our Slack bot. (2) 30-second scan cadence vs. the 45-second cadence common in this space. (3) Anomaly detection — we automatically catch Costco prices near or below spot with zero user configuration. See the comparison table above for the full head-to-head.
Inside the app you get 30 / 60 / 90-day stock history, the live US warehouse map, and zip-code search. For a public overview — current SKUs, typical premium over spot, how often Costco restocks, and how fast bars sell out — see our weekly Costco silver price & restock report, updated every week.
Five minutes, three steps: favorite the warehouses you'd actually drive to, add your cashback stack so prices become your margin, and turn on the alerts that match how you buy. The 5-minute setup guide walks the whole flow with screenshots.
Silver Alerts Premium runs $15 a month. Configure your cashback stack once and the math shows your real margin on every silver product — and if we surface one opportunity you'd have missed in a year, the subscription has already paid for itself.
No contract, no minimum term. Cancel any time and you keep alerts until your billing period ends. We don't bury cancellation in a phone tree.
Silver Alerts Premium pays for itself. Cancel anytime.
