The commissary and exchange are the two biggest on-base shopping benefits you get for serving. Together they cut grocery bills by about 25% and zero out sales tax on everything else. Here is how to use them: who qualifies, what ID works at the gate, and the savings plays most people miss.
TL;DR — What You Need to Know
The Commissary (DeCA)
The Defense Commissary Agency runs 167 commissaries inside the continental US, plus more in Alaska, Hawaii, and overseas. It is a grocery store: dairy, meat, produce, pantry staples, cleaning supplies, baby formula, pet food.
The pricing model is what makes it worth the drive. Commissaries sell items at the cost DeCA paid plus a flat 5% surcharge. The surcharge pays for store construction and equipment, not profit. DeCA is a taxpayer-subsidized benefit measured against a savings mandate set by Congress.
In fiscal year 2024, the average commissary shopper saved 25.5% compared to regional grocery stores. DeCA returned about $1.58 billion in value to patrons that year.
The 5% surcharge on your receipt is a federally mandated fee for facility modernization. There is no state or local sales tax on your grocery bill, even in states that tax food at civilian stores.
What you can pay with: credit/debit cards, Military Star Card, SNAP, WIC, personal checks on most installations, and cash.
The Exchange (PX, BX, NEX, MCX, CGX)
The exchange is the department store on base: clothes, electronics, appliances, furniture, tools, uniforms, cosmetics, and a lot more. Each branch runs its own system:
- AAFES — Army & Air Force Exchange Service. About 99 main PX/BX locations in the US plus stores worldwide.
- NEX — Navy Exchange Service Command.
- MCX — Marine Corps Exchange.
- CGX — Coast Guard Exchange.
The pitch is the same across all four: tax-free pricing that targets Walmart or Amazon. If you live in a state with 8 to 10 percent sales tax, buying a $1,200 TV on base keeps $96 to $120 in your pocket. On appliances or furniture, that is a real number.
Exchanges are non-profit. Earnings feed back into MWR programs — gyms, pools, youth centers, family events. You are saving on the purchase and funding the on-base programs your family uses.
Who Qualifies to Shop
In-store and online rules are different. That is where most people get lost.
In-store shopping (commissary and exchange)
- Active duty across all branches, including Space Force and Coast Guard
- National Guard and Reserve members
- Military retirees
- 100% disabled veterans and Medal of Honor recipients
- Since January 2020: Purple Heart recipients, former POWs, all veterans with a VA-documented service-connected disability (ratings 0% through 90%), and primary family caregivers enrolled in VA’s Comprehensive Assistance for Family Caregivers program
- Authorized dependents of all the above
Online exchange shopping (since November 2017)
All honorably discharged veterans can shop the online exchanges regardless of disability rating: shopmyexchange.com, mynavyexchange.com, shopcgx.com, and mymcx.com. Verify identity once through Vetverify or ID.me when you create the account, then shop tax-free forever.
The 2017 expansion is for exchanges only. Honorably discharged veterans without one of the in-store eligibility categories above cannot order from the commissary's CLICK2GO. CLICK2GO is just an online pickup system for people already eligible in-store.
| Your Status | Commissary In-Store | Exchange In-Store | Exchange Online |
|---|---|---|---|
| Active duty / Guard / Reserve | Yes | Yes | Yes |
| Military retiree | Yes | Yes | Yes |
| 100% disabled veteran | Yes | Yes | Yes |
| Service-connected (0-90%), Purple Heart, former POW, MOH | Yes (since 2020) | Yes (since 2020) | Yes |
| Primary family caregiver (VA CAFC program) | Yes (since 2020) | Yes (since 2020) | No |
| Honorably discharged veteran (no service-connected rating) | No | No | Yes (since 2017) |
| Dependent with DEERS enrollment | Yes | Yes | Yes (tied to sponsor) |
What ID Works at the Gate
This is where most veterans get turned away. A DD-214 alone does not get you past the register. You need one of these:
- CAC — active duty, Guard, and Reserve on active status.
- Next Generation USID — retirees, dependents, and other authorized patrons. Replaced the old DD Form 1173 in 2020.
- VHIC — Veteran Health ID Card, but only if it displays “SERVICE CONNECTED,” “PURPLE HEART,” or “FORMER POW” below your photo on the front. A plain VHIC without one of those designations will not get you in.
Some veterans who qualified under the 2020 expansion have older VHICs without the indicator. Request a reissue through your VA medical center. In the meantime, most installations accept a VA service-connected disability letter or VA caregiver patronage letter paired with a REAL ID-compliant driver's license or US passport. Call the installation visitor center first to confirm.
The Military Star Card
The Military Star Card is AAFES-issued, not a Visa or Mastercard. It is closed-loop — it only works at military exchanges, commissaries, on-base gas stations, and military clothing stores. That limitation is also why it beats commercial cards on fees and financing.
What makes it worth opening:
- 10% off first-day purchases when you open the account. On a washer or a TV, that usually covers the application.
- 2% rewards on every purchase, excluding the Military Clothing Line. Points convert to rewards cards in $20 increments at 2,000 points.
- 0% APR on the Military Clothing Line of Credit for authorized uniform items.
- Periodic 0% promotional financing on electronics, furniture, and appliances. These run year-round, typically 6 to 24 months zero-interest on qualifying purchases.
- No annual fee, no late fee, no over-limit fee.
The card works at every exchange (AAFES, NEX, MCX, CGX) and at all DeCA commissaries. The 2% back stacks on top of your commissary and exchange savings.
Hidden Savings Plays Most People Miss
Case lot sales (commissary)
DeCA runs case lot sales twice a year, usually spring and fall. Pantry staples, paper goods, and shelf-stable items ship in bulk at cost. A single case-lot weekend can drop your grocery bill for a quarter. Check the sales flyer at shop.commissaries.com before each event.
Frozen price program (commissary)
Since 2022, DeCA has held prices flat on more than 1,000 staples. During years of grocery inflation, that program is a big reason the 25% savings gap against civilian stores has held up.
Digital coupons via the Rewards Card (commissary)
Grab a Commissary Rewards Card at customer service for free. Register it at shop.commissaries.com, load digital coupons, and discounts apply at checkout. No clipping.
Military Star financing on big-ticket items (exchange)
Appliances, furniture, and computers on base usually beat Home Depot or Best Buy: no sales tax, 10% off first-day purchases with a new Military Star account, 2% rewards, and often a 0% promotional window. On a $2,500 refrigerator, that stack can run $300 to $400.
Power Pass and seasonal sales (exchange)
Exchanges run Power Pass weekends (extra dollars off over a threshold), tax-refund blowouts, and Veterans Day sales. If you have a big purchase coming, wait for one. Sign up for the exchange email list so you do not miss it.
Common Myths, Debunked
- “The commissary is only for active duty.” Wrong. Retirees have always been in. Since 2020, service-connected disabled veterans, Purple Heart recipients, former POWs, MOH recipients, and designated caregivers are in too — about 4.1 million more eligible shoppers, most of whom still do not know.
- “A DD-214 gets you into the commissary.” Wrong. A DD-214 proves you served, but it is not a shopping credential. You need a CAC, USID, or VHIC with the right designation. Bring the DD-214 as a backup.
- “Exchanges are tax-free because they are on federal property.” Partially right. The federal-property exemption is real. The reason the tax-free benefit also extends to online purchases shipped to your home is that exchanges are non-appropriated fund instrumentalities — a legal category that carries the exemption with them.
- “Savings are not that different from Walmart.” Wrong on average. DeCA’s annual Savings Assessment measures regional price baskets. The 25% average number is real and audited.
- “You cannot use SNAP or WIC at the commissary.” Wrong. Both are accepted. Commissary plus WIC stacks well for junior enlisted families.
- “Every honorably discharged vet can shop the commissary online.” Wrong. Online exchange shopping has been open to all honorably discharged veterans since 2017. The commissary’s CLICK2GO is a different system and only serves customers already eligible in-store.
Common Questions
Can my spouse or kids shop without me?
Yes, if they are enrolled in DEERS and carry a valid USID or dependent CAC. They use their own card at the register.
Can I bring a friend shopping with me?
A friend can walk the store with you, but purchases must be rung up under an eligible shopper’s ID. Reselling commissary or exchange goods to non-eligible people is prohibited.
Does my Military Star Card work at off-base retailers?
No. Closed-loop only: military exchanges, commissaries, on-base gas stations, and military clothing stores. That is why it can offer 0% financing and zero fees.
What if a commissary item is priced higher than Walmart?
DeCA prices basket-wide, not SKU-by-SKU. A single item may cost more some weeks, but the average basket still comes out 25% cheaper. If a specific item is cheaper elsewhere, buy it elsewhere.
Can I shop the exchange online from overseas?
Yes, if you are military, retiree, or an eligible veteran. Shipping is available to APO/FPO addresses and most international locations. Tax-free pricing still applies.
My VHIC does not say “SERVICE CONNECTED” but I have a disability rating — what now?
Request a new VHIC at your local VA medical center. The updated card prints the designation under your photo. While you wait, bring your VA disability rating letter plus a REAL ID and call the visitor center ahead to confirm what they will accept.
