How to Save on Groceries with Credit Cards, Delivery Apps, and Cashback Tools
A practical guide to reducing grocery costs by combining credit card perks, delivery service credits, discounted gift cards, and cashback apps.
Grocery spending is one of the most consistent expense categories in most households, which makes it one of the most valuable to optimize. The good news is that grocery savings tools are better than they've ever been — and they stack.
Here's a practical approach that combines credit card perks, delivery service credits, discounted gift cards, and cashback apps.
Credit Cards with Strong Grocery Earning Rates
American Express Gold Card
The American Express Gold Card earns 4x Membership Rewards at U.S. supermarkets (up to $25,000 per year, then 1x). On grocery spending of $500/month, that's 24,000 points per year worth roughly $480–$600 depending on how you redeem them.
The card also includes up to $120 per year in Uber Cash ($10/month) and up to $120 per year in dining credits — both useful alongside grocery spending.
Blue Cash Preferred from American Express
The Blue Cash Preferred earns 6% cash back at U.S. supermarkets (up to $6,000 per year, then 1%). This is the strongest cash back rate available on grocery spending without category caps under $6,000. At $500/month in supermarket spending, the 6% earns $360 per year in cash back before fees.
Annual fee: $95 (waived the first year).
Chase Freedom Flex
The Chase Freedom Flex includes rotating quarterly bonus categories that have historically featured grocery stores and warehouse clubs. When active, the card earns 5x on up to $1,500 in grocery spending per quarter — $75 worth of Ultimate Rewards points at minimum. Activate each quarter to capture these bonuses.
Delivery Service Credits
Several credit cards include monthly credits for grocery delivery services. These reduce the effective cost of delivery to near zero.
Instacart:
The Chase Sapphire Preferred and Chase Sapphire Reserve include monthly Instacart credits. The Reserve includes a complimentary Instacart+ membership. Link your Chase card to your Instacart account to apply credits automatically at checkout. The credits cover the delivery fee on most orders over $35.
DoorDash:
Both Sapphire cards include monthly DoorDash credits ($10 on Preferred, $20 on Reserve). Costco also sells DoorDash gift cards at a discount — buying at a discount and using with the monthly credit stretches the value further.
Walmart+:
The American Express Business Gold Card includes a complimentary Walmart+ membership. Walmart+ covers free grocery delivery with prices matching in-store, which is the most cost-efficient delivery option if there's a Walmart nearby.
Discounted Gift Cards
For grocery stores that sell gift cards at a discount — or for buying DoorDash, Uber Eats, and Instacart credit in advance — the usual sources apply:
- Costco sells DoorDash and Uber Eats gift cards at roughly 20% below face value
- Grocery store promotions occasionally include bonus value on gift card purchases (e.g., $10 off a Best Buy gift card with a grocery purchase — check your store's weekly flyer)
- Secondary markets like Raise sometimes have discounted cards for major chains
Pay for gift cards with a card that earns bonus points at the purchase location to stack savings.
Cashback Apps
Ibotta pays cash back on specific grocery items after you scan your receipt. You claim offers for specific products before shopping, buy them, and scan the receipt to receive the rebate. It's most valuable when you're buying items you'd purchase anyway (produce, dairy, national brands on sale).
Rakuten covers online grocery ordering at Instacart, Amazon Fresh, and other services. Shopping through Rakuten's link before placing an order adds 1–5% back.
Coupons.com and store apps offer digital coupons for both in-store and delivery orders. Most major chains (Kroger, Publix, Safeway) have their own apps with digital coupons that apply automatically at checkout.
Price Comparison
The Flipp app aggregates weekly store circulars and lets you compare prices and BOGO deals across nearby stores. Useful for planning which store to shop at for specific items, or confirming whether a warehouse price beats a sale price.
Store brands and generic products typically run 20–30% cheaper than name brands with comparable quality on most staple items.
Putting It Together
A practical weekly grocery stack:
- Use the Amex Gold Card (4x) or Blue Cash Preferred (6%) as your primary grocery card
- Activate Chase Freedom Flex quarterly bonuses when grocery categories appear
- Apply delivery service credits (Instacart, DoorDash) to delivery orders
- Use Ibotta for specific item cashback on receipt scan
- Check Flipp for weekly deals before choosing which store to visit
The layers compound. At $600/month in grocery spending, the combination of a 4–6% earning card, periodic delivery credits, and Ibotta rebates can add up to $350–$500 in annual savings.
Bottom Line
The biggest single win is using a card with a strong grocery earning rate — Amex Gold (4x points) or Blue Cash Preferred (6% cash back) — and keeping your grocery spending concentrated there. Layer in the delivery credits and Ibotta for additional savings on top. Review your options annually since card benefits and store promotions change.
