You can return baby formula at most major retailers if the container is unopened, sealed, and brought back within the store’s return window with a receipt. Windows run from about 30 days at Amazon to 90 days at Walmart and Target, with Costco the most flexible. Opened formula is almost never returnable, formula bought with WIC benefits has to be handled through the WIC clinic rather than the store, and recalled formula follows separate rules that override the usual limits.
Return Windows at the Major Retailers
Every chain sets its own deadline, and the spread is wider than most parents expect:
- Walmart: 90 days from purchase with a receipt.
- Target: 90 days for unopened items in new condition.
- CVS: 60 days from purchase for new, unopened items.
- Amazon: 30 days from delivery for items in original, unused condition.
- Costco: no fixed window under its satisfaction guarantee, making it the most flexible.
- Kroger: accepts formula returns but requires a receipt.1Kroger. Return Policy – How to Return Items
These windows cover standard purchases. If you bought formula through a third-party marketplace seller on Amazon or Walmart.com, that seller’s policy can override the platform’s default, so check the order details before you assume the standard window applies.
What Condition the Formula Has to Be In
Retailers are stricter about formula than almost any other product, and the reason is practical. Once a container leaves the store, no one can guarantee how it was stored. A can that spent a weekend in a hot car may look fine and still be compromised. Returned infant formula is never put back on shelves or resold.2Infant Nutrition Council of America.

To qualify for a return almost anywhere, your formula needs to meet three conditions. It has to be unopened, with the original packaging and seal intact; once that seal is broken, the return is essentially off the table. It has to be inside the store’s return window, counted from the purchase date or the delivery date for online orders. And you need proof of purchase. A receipt is standard. Some stores can look up a transaction from a credit card, loyalty account, or app history, but don’t rely on it. Kroger, for instance, explicitly requires a receipt for formula.1Kroger. Return Policy – How to Return Items
Two situations sit outside those rules. If the formula was already expired when you bought it, or the packaging is visibly defective (a dented can, a broken seal, a damaged label), most retailers will take it back even when the normal conditions aren’t met. Retailers are expected to inspect and rotate formula so nothing on the shelf is past its use-by date.2Infant Nutrition Council of America. Resource Guide for Retailers on Infant Formula Returns
Opened Formula Is Almost Always Non-Returnable
This is where most parents hit a wall. Your pediatrician switches your baby to a new brand, you buy a can, your baby refuses it or reacts badly after a feeding or two, and now you have an open container you can’t use. Nearly every retailer refuses returns on opened formula. The health risk is too high for the store to accept it, and since returned formula can’t be reshelved anyway, there’s no way for the retailer to absorb the cost.
The narrow exception is a manufacturer defect or contamination. If you open a can and find something clearly wrong (an unusual smell, discoloration, foreign material), contact the store and the manufacturer. In those cases both sides will usually work with you because the problem originated on their end. Keep the product, the container, and your receipt.
Formula Bought With WIC Benefits
Formula purchased with WIC benefits generally cannot be returned to the store for a refund or exchange. Kroger’s policy states this outright.1Kroger. Return Policy – How to Return Items The restriction exists because WIC benefits are tied to specific products and quantities approved for each participant, and the transaction runs differently from a standard cash or card purchase.
If your baby needs a different formula than the one WIC provided, the swap happens at your local WIC clinic, not the store. A WIC nutritionist can update the food prescription and exchange the formula type on an ounce-for-ounce basis. Bring any unopened cans to the appointment, and the new benefits load to your EBT account.
Selling or trading WIC-purchased formula is illegal, whether in person or online. It can result in removal from the WIC program, legal action, and a requirement to repay the benefits.
Recalled Formula Follows Different Rules
When the FDA determines that infant formula is contaminated or poses a health risk, the manufacturer has to pull the product from shelves all the way down to the retail level.3eCFR. 21 CFR 107.200 – Food and Drug Administration-Required Recall Manufacturers can also initiate voluntary recalls on their own.4eCFR. 21 CFR Part 107 Subpart E – Infant Formula Recalls
For a consumer trying to return recalled formula, the usual rules loosen considerably:
- Receipt requirements are usually waived. The goal is getting unsafe formula out of homes, not verifying purchase history.
- The return window doesn’t apply. You can return the product no matter when you bought it.
- Opened containers are included. Whether the seal is broken doesn’t matter.
- You may deal with the manufacturer directly. Some recalls send you back to the store; others route refunds through the manufacturer. The 2022 Similac recall let consumers either return the product to the retailer or request a refund through the manufacturer’s website.5Similac Recall. Refund FAQs
Checking Whether Your Formula Is Recalled
Recall notices identify affected products by specific lot codes and expiration dates printed on the container, usually on the bottom of the can.6Food and Drug Administration. Investigation of Cronobacter Infections from Powdered Infant Formula Manufacturers often set up lot-number lookup tools during a recall so you can check your exact container. The FDA posts all active recalls on its website; check there first, then the manufacturer’s site, and don’t rely on secondhand social media posts for lot numbers, which frequently contain errors.
If You Can’t Return It
Outside the return window, missing a receipt, or holding an opened can, you still have options before the formula hits the trash.
Donate It
Food banks and community organizations often accept donations of unopened, unexpired baby formula. Local shelters, churches, and crisis pregnancy centers frequently take it too. Call ahead to confirm they’ll accept your specific type, since some places restrict powdered versus liquid. The formula needs to be sealed, within its use-by date, and in undamaged packaging.
Don’t Resell It Online
Reselling unused formula on eBay, Facebook Marketplace, or Craigslist sounds practical but carries real problems. eBay restricts baby formula sales to established business sellers with at least 90 days of active selling history, 100 or more transactions, and at least $1,000 in sales over the past year.7eBay. Products with Eligibility Requirements Policy Casual sellers don’t qualify.
Safety is the bigger issue. Formula from unknown sellers has been found with tampered expiration dates, containers swapped to imitate expensive specialty formulas, and products stored in damaging conditions. And if the formula was bought with WIC benefits, selling it is a federal offense with legal and program consequences. Donating unopened formula to a family in need or a food bank does more good and carries none of that exposure.
