The problem
The same cart costs a different amount at every store.
Milk's cheapest at one store this week, diapers at another. Finding out yourself means searching forty items across six sites, matching names and sizes, and adding up delivery fees — so most people skip it and overpay. CartSplit does that item-by-item check for you, splits your list to the cheapest store for each thing, and re-checks every price in your cart before you buy.

Real prices from real shops — verified receipts, order confirmations, and live store sessions, never coupon feeds. Every verified shop makes your area's price map a little sharper.

Your cart splits itself
Every item goes to whichever of your stores sells it cheapest — delivery fees counted. Then the Chrome extension fills each store's cart for you, on your computer, in one click.

You save — for the honest reason
Not coupons. Not loyalty points. Not a “5% off” sticker on a marked-up price. You save because every item came from the store with the lowest real price.
No deal theater
We compare prices. We don't perform them.
Sale tags love a story: mark it up, cross it out, call it 5% off. CartSplit ignores the story and reads one number — what the item costs at each of your stores, right now, delivery fees included. If splitting your cart doesn't actually save money that week, it tells you that too.
- Real shelf prices from your stores — never averages or estimates
- Delivery fees counted before an extra store is worth it
- One tap to check out at each store, or find your items on Instacart

Receipts stay in your browser
Your purchase history lives in your own browser's storage, not our database — our servers keep just your zip code and store prices.
Never sold, never tracked for ads
We don't sell your data and we don't run ad trackers. You pay $4.99/mo and can cancel anytime — your data is never the product.
Real shelf prices, plainly labeled
Every comparison shows where each price came from and when. If splitting doesn't actually save money that week, it says so.
Fair questions
Do I have to clip coupons or scan loyalty codes?
No. CartSplit doesn't do coupons at all — it compares the actual shelf price of each item across the stores you already shop, and sends each item to whichever store sells it cheapest that week.
Which stores does it work with?
Walmart, H-E-B, Costco, Kroger, Target, Whole Foods, and Aldi today. You pick your stores during setup, and prices come from your own receipts, the free Chrome extension, or automatic price checks you authorize.
How do the carts actually get filled?
The free Chrome extension builds each store's cart for you, on your own computer, in your own logged-in session — one click per split. You still review everything and check out yourself.
What does $4.99/mo get me — and can I try it first?
The subscription covers everything: splits at current prices, receipt imports, price watching, and one-click cart fills. Try the interactive demo with sample data first — no card, no account. Cancel anytime from your account menu.
