Gold has been on a remarkable run. As of early 2025, the spot price had already climbed past $2,850 per ounce and continued higher through the year, hitting record territory and pulling in a new wave of retail buyers who had never considered precious metals before.
Two unlikely competitors have emerged as go-to options for everyday investors: APMEX, the Oklahoma City-based specialist that has processed over $11 billion in transactions since 2000, and Costco, the warehouse club that quietly became one of the country's top gold retailers after launching its bullion program in October 2023.
They could not be more different. One is a dedicated precious metals exchange with over 20,000 products. The other sells gold bars next to bulk olive oil and rotisserie chickens. Choosing between them depends entirely on what kind of buyer you are.
Key Takeaways
- Costco offers some of the lowest premiums in the market (around 2% over spot), but inventory sells out fast and returns are not accepted on precious metals.
- APMEX carries over 20,000 products across gold, silver, platinum, and palladium, with a buyback program, IRA options, and secure vault storage at higher premiums.
- Costco suits the casual buyer looking for a simple, low-cost gold bar; APMEX suits serious collectors, active investors, and anyone who needs flexibility to sell.

Company Backgrounds
APMEX short for American Precious Metals Exchange was founded in 1999 by Scott Thomas and launched online in 2000. It has since sold more than 130 million ounces of gold and silver to over 1.8 million customers across 60+ countries.
The company holds an A+ rating from the Better Business Bureau and ships to international buyers, which most competitors do not. It operates as a specialist: this is all it does, and its product catalog reflects that focus.
Costco needs no introduction as a retailer, but its precious metals chapter is recent. The company began selling one-ounce gold bars online in 2023 and expanded into silver and platinum shortly after.
The program grew faster than almost anyone expected. Wells Fargo analysts estimated Costco was generating between $100 million and $200 million per month from gold bar sales by early 2025, enough for the company to list gold among its top-selling product categories in its quarterly earnings report.
That kind of volume from a warehouse chain is genuinely unusual.
Product Selection: No Contest
This is where the two companies diverge most sharply. APMEX carries over 20,000 individual products: gold and silver bars in weights from 1 gram to 400 oz, coins from dozens of world mints, platinum and palladium, numismatic and graded coins, pre-1933 U.S. gold, exclusive mint releases, and junk silver.
It is an official dealer with PCGS (Professional Coin Grading Service) and partners directly with major mints to release exclusive designs unavailable elsewhere.
Costco's precious metals page, by contrast, lists a small rotating selection of items. Typical offerings include a handful of one-ounce gold bar options from producers like Rand Refinery and PAMP Suisse, a 100-gram gold bar, sets of silver coins in bulk (20- or 25-count), and a PAMP Suisse platinum bar.
The selection changes based on supply. Items frequently go out of stock within hours of being listed.
| Category | APMEX | Costco |
|---|---|---|
| Total SKUs | 20,000+ | ~5–10 at any given time |
| Gold bars | Yes (multiple weights/mints) | Yes (1 oz and 100g, limited brands) |
| Silver coins/bars | Yes (extensive) | Limited (bulk sets only) |
| Platinum | Yes | Yes (one bar) |
| Palladium | Yes | No |
| Numismatics/collectibles | Yes (extensive) | No |
| IRA-eligible products | Yes | No |

Pricing and Premiums
Costco's biggest advantage is price. The company marks up gold at roughly 2% over spot, which sits at the low end of the industry range (premiums typically run from 1% to 30% depending on the dealer and product).
In February 2025, a one-ounce gold bar at Costco was priced just over $2,900 when spot was approximately $2,850. By October 2025, a one-ounce bar from Rand Refinery was listed at $4,179.99 with spot trading around $4,080 still a narrow spread.
Executive members who pay an additional $65 annually also earn a 2% reward on purchases, which on a $4,100 gold bar works out to about $82, effectively covering part of the membership upgrade cost.
APMEX's premiums are higher, and that gap is a known trade-off. For common bullion products like American Eagles or generic bars, competitors like JM Bullion and SD Bullion regularly beat APMEX on price.
However, for rare coins, exclusive releases, or international shipments, APMEX often has no real alternative. The platform earns its premium through selection depth, not price leadership.
Buyers who pay with a bank wire or check also receive a 4% discount; credit card and crypto payments carry a 4% surcharge instead.
A practical pricing comparison for a one-ounce gold bar (based on available 2024–2025 market data):
| Costco | APMEX (typical) | |
|---|---|---|
| Premium over spot | ~2% | 3%–8% depending on product |
| Shipping | Free (for members) | Free on orders over $199 |
| Membership required | Yes ($65–$130/year) | No |
| Credit card surcharge | None | 4% |
| Wire/check discount | No | 4% |
Availability and Purchase Limits
Costco's inventory situation deserves its own discussion. Gold bars routinely sell out within hours of a new listing appearing on Costco.com.
Demand has been intense enough that Costco tightened its purchase limits in May 2025: buyers are now limited to one transaction per membership, with a maximum of two units per 24-hour window.
Costco also does not sell precious metals in Louisiana, Nevada, or Puerto Rico, and members in some regions have limited or no in-store access to metals at all.
APMEX does not impose those kinds of restrictions on standard purchases. Buyers can order across a full range of weights and quantities, set up automated recurring purchases through the AutoInvest feature, and access live spot price charts and alerts at any hour.
For buyers who want to build a position gradually or scale up over time, that flexibility matters.
Buyback and Liquidity
This is where Costco falls short and it's worth understanding before making a purchase. Once a member buys gold, silver, or platinum from Costco, the sale is final.
Precious metals are explicitly excluded from Costco's otherwise generous return policy. There is no buyback program, no resale desk, and no price adjustment after purchase. Sellers are left to find their own buyers, which in practice means coin shops (who price below spot) or private dealers.
APMEX runs a structured buyback program through its "Sell to Us" portal. The minimum sale is $1,000. Sellers request a quote, lock in a price by phone (protecting against market movement during transit), ship their metals, and typically receive payment the business day after APMEX receives the items.
If metals are stored through APMEX's vault partner Citadel, shipping fees for the sellback are waived. Some customers report that APMEX buyback quotes run lower than expected, and there have been complaints about quotes changing after metals arrive, so it's worth comparing offers before committing.
Storage Options
Costco delivers metals to your door via UPS or FedEx in about 3–5 business days. After that, storage is entirely the buyer's problem.
Standard homeowners insurance policies typically do not cover the full value of precious metals, so buyers need to arrange separate coverage or a secure storage solution a home safe, safety deposit box, or third-party vault.
Those costs add to the effective total price of the investment.
APMEX offers institutional storage through Citadel, which operates within Brink's Global Services vault infrastructure. Storage fees run between 0.45% and 0.55% annually, with a minimum monthly fee of $15 for portfolios under $25,000.
It is not free, but it is insured, professionally managed, and convenient for investors who do not want metals sitting at home.
APMEX also offers OneGold, a digital ownership platform built in partnership with Sprott Asset Management, where buyers can hold metals-backed digital assets stored at Loomis International and the Royal Canadian Mint without needing physical delivery at all.
IRA and Retirement Investing
Costco offers no pathway to hold its precious metals inside a tax-advantaged retirement account. Most retail buyers are not looking for IRA products when picking up a gold bar, but it is a real gap for anyone with a longer-term strategy in mind.
APMEX supports precious metals IRAs through IRS-approved custodians including Equity Institutional, The Entrust Group, GoldStar Trust, and Strata Trust Company.
The minimum investment is $2,000, with storage fees starting at $15 per month. Costco does not offer this at all.
Customer Experience
Costco's precious metals operation is transactional by design. No educational tools, no live spot charts, no portfolio tracking, no specialists to call.
You browse, you buy if it's in stock, and a delivery arrives in 3–5 business days. For many buyers, that simplicity is the point.
APMEX provides a knowledge center, a mobile app with live price alerts, portfolio tracking, a cost calculator, and a customer service team reachable by phone, email, and live chat on weekdays.
Its review scores are split: 4.9 out of 5 on Shopper Approved from over 262,000 reviews, but 1.6 out of 5 on Trustpilot. The low Trustpilot score reflects real complaints about premiums, shipping delays, and slow response times during busy periods.
APMEX carries an A+ BBB rating and has operated for 25 years, so credibility is not in question consistency sometimes is.

Conclusion
Costco wins on price and simplicity for a single gold bar purchase, but the lack of returns, no buyback program, thin inventory, and zero IRA infrastructure make it a poor fit for anyone treating precious metals as a serious investment strategy.
APMEX charges more but delivers the infrastructure to match: depth of selection, a structured way to sell, vault storage, IRA access, and tools for investors who buy more than once.
