The Military Family Money-Saving Guide (Commissary, Exchange & PCS)
How military families can save the most — using the commissary's ~25% grocery savings, tax-free Exchange shopping, the MILITARY STAR card, and smart PCS-move timing.
Military families have savings tools no civilian shopper gets — the commissary, the Exchange, and benefits built around military life. Used together, they add up fast. Here's how to get the most out of each, plus how to time the big stuff around a PCS.
1. The commissary: your biggest grocery lever
The on-base commissary is required by law to save shoppers money versus local stores, and it delivers an average of about 23.7% savings — with leadership targeting 25%+ worldwide. The Defense Department has also pushed the price of staples like bread, milk, and eggs down a further 3–5%. For a family that buys groceries every week, that's the single biggest recurring saving on this page.
A few things to know: - Manufacturer coupons are welcome. The commissary is one of the best places to stack a coupon on top of the already-lower shelf price — see our coupon-stacking guide. - Still check the unit price. Lower-on-average doesn't mean lower on every item; a warehouse club or a sale off-base can occasionally beat it. Our unit price guide shows how to compare fairly. - Find your store fast. Our Military section lets you pick your base's commissary and jump straight to this week's sales flyer and digital coupons.
2. The Exchange: tax-free, every time
Every purchase at the Exchange — in store and online — is tax-free, which saves you 5–10% right off the top depending on your state, on top of competitive prices and price-matching. Online orders ship free on totals of $49+ (or with a MILITARY STAR card). For non-grocery household goods, electronics, and clothing, that tax-free margin is real money on every cart.
3. The MILITARY STAR card (use it deliberately)
If you shop the Exchange regularly, the MILITARY STAR card stacks extra value: - 2% rewards on most purchases, - a 10% discount on your first day of purchases after approval, and - periodic special financing (0% APR for 6–12 months on larger purchases).
The honest caveat: a store card is only a deal if you pay it off — interest erases the rewards fast. Treat the financing as a tool for a planned big purchase (think furnishing a home after a move), not everyday spending.
4. Time the big purchases around your PCS
A Permanent Change of Station is when the most money moves at once — and where good timing pays off most. - Know your entitlements. The military offers PCS entitlements to help cover the move; understand what's reimbursed before you spend out of pocket. - Buy household bulk before you move, not after. Arriving at a new base with a stocked pantry of shelf-stable essentials beats paying full price during the chaos of settling in. Our seasonal stock-up calendar shows when each category hits its lowest — line your big buys up with those windows. - Furnish with tax-free + financing. Replacing appliances or furniture after a move is exactly where the Exchange's tax-free pricing and the STAR card's interest-free financing shine — instead of a high-interest civilian card. - Restock with a plan. A simple repeatable list keeps the post-move resupply cheap — see our monthly household shopping list.
5. Don't leave the family benefits on the table
- New babies & kids: brands and programs give a surprising amount away — see our new-parent savings guide and new-parent freebies.
- Watch the "lowest in 90 days" signal. On each deal here we track price history and flag genuine lows — pair that with your tax-free or commissary pricing for the best of both.
The bottom line
Stack the benefits in this order: groceries at the commissary, everything else tax-free at the Exchange, rewards/financing via STAR for planned big buys, and time your bulk stock-ups to the seasonal calendar — especially around a PCS. None of it requires extra effort once it's a habit; it's just using the benefits you've already earned.
