Everything you need

A complete arbitrage workflow. Built for the way you actually flip gold.

Five tools that do the heavy lifting — inventory, payouts, profit math, alerts, and SMS — plus the secondary surfaces that round it out. Every section below maps to a screen in the product.

01 · Payout Comparisons

58 products. Four live brokers. Cashback math baked in.

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.

  • BGS, DCB, CollectPure, Ali Incentive — every bid on every product.
  • Premium-over-spot badge next to every Costco price — instantly readable.
  • Per-payment-method cashback shown inline — see your real margin, not the headline bid.
Broker Prices · 58 products LIVE

02 · Inventory Tracking

90 days of stock history. Every warehouse on the map.

Watch how gold and silver inventory has moved across Costco's entire US warehouse network — overlaid against the gold spot price so you can see exactly when stock spikes and crashes happen. Drop in your zip code to find the closest stores with current inventory.

  • 30 / 60 / 90-day history charted against the gold-price line.
  • Live US warehouse map — green dots are stores with current stock.
  • Warehouse Finder — zip-code search returns the closest restock candidates.

03 · Profit & Margin Tools

Multiple profiles for the way you actually buy.

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.

  • Unlimited profiles — one per card, address, or strategy.
  • Drives every alert, dashboard, and broker comparison automatically.
  • All active profiles in one grid — see every cashback path side-by-side, no switching needed.
Purchase Profiles · 3 active
Three purchase profile cards: Capital One VentureX, Citi Plus Membership, and Venmo
04 · Alert Engine

Profit windows and price anomalies. One page, one workflow.

Set a profit threshold against the brokers and profiles you trust — or let the system flag any Costco product priced near or below spot, automatically. Every rule shows current status, channels, last-fired time, and target config so you always know what's running.

  • Profit Alerts — set a threshold, pick brokers + profile, get notified when it clears.
  • Price Anomalies — automatic, no setup. The scanner catches anything near or below spot.
  • Multi-channel delivery · per-alert cooldown · status timestamps on every rule.

05 · SMS-First Delivery

When the window is minutes, the channel is your phone.

Gold is at all-time highs and the sub-1% premium windows are tiny — sometimes seconds, rarely more than minutes. SMS is the only channel that beats those numbers. We bake the SKU, premium tier, store distance, and a one-tap product link into every text, so you can move before anyone else has even opened their email.

  • Brand-prefixed so you can filter and search in Messages.
  • Quiet hours respected — drops messages, doesn't defer them.
  • Max Stacker fans out to SMS + Email + Push in parallel.

Four more surfaces that round out the product.

Persistent · no cooldown

Spot Price Alerts

Get notified when gold or silver crosses your target threshold. Single-fire by design.

Au + Ag · per-tenant

Profit Dashboard

Track every Costco buy and broker sell. P&L, hold time, and cost-basis math all roll up automatically.

Why us

Faster than what you've used. Built for the way the market actually moves.

Three things we do that nobody else in this space does — and a head-to-head against the typical alternatives.

Speed

30-second scan cadence

Our hot tier polls Costco's bulk API 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.

33%faster than typical
Channels

SMS, Slack, and everything else

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.

4delivery channels · 1 community

Honesty

Anomaly detection, built-in

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.

0configuration needed
Transparency

Show your work, always

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".

How it works

From inventory drop to your phone — under a minute.

No user-driven scans. No daily digest. The pipeline is built like a trading bus: continuous, batched, and out the door the second a decision is made.

T+0s

Bulk API tick

Costco's precious-metals search endpoint returns the live availability table.

T+0.4s

Per-SKU confirm

Five consecutive matching scans confirm a restock. False detections drop out automatically.

T+0.9s

Match alerts against personalized profit thresholds, premium tiers, and cooldowns.

T+1.2s

Out to you

SMS, email, and push dispatched in parallel — each with a millisecond timestamp logged in your alert history.

By the numbers

Built like the trading desk it is.

Real product metrics — not marketing math.

<60seconds

End-to-end alert latency

From a Costco inventory change to an SMS on your phone — typically under one minute, often closer to 30 seconds.

5scans

Confirmation depth

Every restock or out-of-stock event must pass five consecutive matching scans before an alert fires. False positives are designed out.

Products in the catalog

Every gold and silver SKU Costco currently sells — bars, coins, and ShipIt-eligible variants — tracked automatically the moment it lists.

Pricing

The Max Stacker pays for itself.

One bar caught at the right premium clears the cost of a full year. Add a credit-card signup bonus on the same buy, and the math goes from "pays for itself" to "pays for the next three years." You don't need a string of wins — you need one.

The math is on your side

One additional bar. One signup bonus. The year is covered.

Max Stacker runs $180 / year. A single PAMP 1 oz at under 1.5% over spot with cashback nets $70–$100. An anomaly catch (Costco listing near or below spot) clears $200+ on its own. A first-buy credit-card signup bonus typically adds $200–$600 on top. Any one of those — let alone the combination — and your subscription is already in the green for the year.

FAQ

Sharp questions. Straight answers.

How fast are the alerts, really?

The bulk API runs on a 30-second hot tier. The end-to-end path from a Costco 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.

Is there a daily search limit?

No. Max Stacker comes with unlimited searches — the product does the searching for you anyway, since it scans the catalog continuously on a 30-second cadence.

Which brokers do you compare?

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.

How do I know an alert is real and not a false positive?

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.

How fast does each notification actually fire?

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.

What does the SMS look like?

Every text is brand-prefixed with [Gold 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.

How is this different from other tools?

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.

Is Max Stacker really worth $15 / month?

Max Stacker runs $180 a year. A single PAMP 1 oz purchase at under 1.5% over spot nets $70–$100 after cashback and broker payout. A single anomaly catch (a Costco listing near or below spot) clears $200+ on its own. If we surface one opportunity you'd have missed in a year, the subscription has already paid for itself — and most users hit that mark in week one.

Am I locked in?

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.

The next gold window opens
without warning.

Max Stacker pays for itself in one trade. SMS in under a minute. Cancel anytime.
