Hell of a week last week for stackers and flippers, plenty of deals with some even going for below spot!

My warehouse hadn't repriced. The tag still said $4,089.99 while spot was $4,231.70, so I bought 5 and sold them the same morning. Net $847.55.

I posted this morning that Costco moved its 1 oz tag to $4,169.99 across 48 warehouses. Mine was not one of them. The bars were sitting there at yesterday's price, about 3.3% under spot before any cashback, which is not a thing that is supposed to happen.

I put $1,900 of it on a 3% card and the rest on a 2% card, then sold all five to BGS at $4,173.90 each.

That is $169.51 a bar, 4.2% on the $20,021.95 that actually left my account.

Before anyone reads this as a repeatable strategy:

• This was one store on one morning. The reprice is rolling out unevenly and most warehouses already read $4,169.99. At that price the same trade is a fraction of this.
• The whole thing exists because gold moved $153.00 in 24 hours and Costco's sticker moves in steps. It is not Costco selling gold cheaply, it is Costco not repricing fast enough. When the sticker catches up, this closes.
• The BGS number is what it paid this morning. That bid tracks spot, so it falls with spot.
• The $428.00 of cashback is a third of the profit. Without the card stack this is a much thinner trade.

This sub tracks Costco's gold and silver inventory — every US warehouse, every online listing — and posts what actually happened each day, with the math shown.

If you're new: Costco sells gold bars (PAMP, Rand, Buffalos) in warehouses and on costco.com — and most of the time they're priced nowhere near a profitable flip. The interesting moments come when the spot market moves fast and Costco's sticker lags behind it: for a window, the price sits unusually close to what bullion dealers will pay, sometimes close enough that membership cashback pushes the math positive. Those lag windows are what this sub records — what showed up, where, at what price, and whether the math worked. They can close fast: the fastest online sellout we've measured in the last 30 days was just under 6 minutes (as of Aug 1, 2026).

What gets posted here daily: a report image (morning snapshot — warehouse counts by state, in-store shelf prices, spot) and a first comment with that day's finding and its arithmetic, every number stamped with when it was pulled.

The flip math, since it comes up constantly. Some buyers flip the bars to bullion dealers that post buyback bids. The honest version of that math is: broker buyback bid (minus any venue fee) − Costco price + card cashback (2% Executive membership + 2% Citi Costco card). Shipping and your time are not in the table. A real example from August 1, 2026:

Numbers like these move daily — sometimes negative. Six states currently tax bullion at this size, which flips small wins into losses, so the daily posts carry a per-state line when it matters.

How we describe premiums over spot, so the shorthand makes sense: under 1% is exceptional, under 1.5% great, under 2.5% fair, above that poor.

The other reason people watch this: manufactured spending. If you're chasing a credit-card sign-up bonus with a minimum-spend requirement and a deadline, a gold bar is a large purchase you can recover most of by reselling. The closer to spot you buy, the less that round trip costs — which is why the premium bands above matter even on days when the flip itself is negative: a cheap round trip can be worth it when the real payoff is the bonus.

What makes this sub work is ground truth: if you're at a warehouse, post what's on the floor — store state, the shelf tag price, and the date. Tag photos welcome. Flip results with real numbers (including the ones that lost money) are the most useful posts here.

So introduce yourself below: which state's Costco do you check, and what was on the gold shelf last time you looked?

I build and run the tracker behind the daily reports — costcogoldinventory.com. A few of us watch restock windows live in a small Slack (open invite). Not affiliated with Costco. Not financial advice.

Lucky for me my local warehouse had inventory this morning even after it being profitable to buy them all day yesterday!
