Compare supermarket prices in Argentina and see today's discounts from your AI assistant

How much milk costs at each supermarket, where to buy cooking oil near your home, or what discount your card gives you today are questions that normally take five different apps to answer. With Argentina Data MCP, your AI assistant answers them with the prices the chains report to SEPA (the government's supermarket price dataset, the same system behind Precios Claros) and with the promotions currently in force.

SEPA is the system through which supermarket chains publish the price of every product at every sucursal (branch) every day. Argentina Data MCP loads it daily: over 70,000 products from 19 chains, with SEPA program prices and, as a complement, the chains' own online catalogs. On top of that you can search for a product, compare its price across chains, find the cheapest branch near an address and cross it with discounts from banks, digital wallets and loyalty programs to find out your real best price.

Prices are the ones reported by the chains, not a shelf survey, and every answer states the date they are from.

What you can ask

  • How much is whole milk at supermarkets near Av. Corrientes 1234?
  • Which supermarket has the cheapest 2.25-liter Coca-Cola?
  • Which branch near Av. Cabildo 2000 has the cheapest sunflower oil?
  • What supermarket discounts are there today with a Galicia card?
  • What day is best to shop at Coto with a Banco Nación card?
  • What promotions does Carrefour have today?
  • What's the best price on rice near my home if I pay with Mercado Pago?
  • Make me a list with yerba, sugar and pasta and tell me which chain is cheapest for each item

What you can compare

  • Search for a product and see its price across chains, filtered by area if you give it an address.
  • Compare across chains: which one is cheapest and which is most expensive for that product, and how big the gap is.
  • The cheapest branch near you: crosses prices by chain with the promotions in force at each branch around an address.
  • A chain's promotions: which products are on sale today, with list price, promotional price and percentage saved.
  • Discounts by payment method: which day and with which card, digital wallet or loyalty program there is a discount at each chain, with its caps.
  • Your personalized price: the product price minus the supermarket's promotion minus your payment method's discount, so you know what you actually pay.

How to ask so the answer is useful

It works best with specific products: "1-liter whole milk" or "1.5-liter sunflower oil" give better results than "dairy". If you want to compare brands, name the brand; if you want the cheapest regardless of brand, say so and the assistant compares by price per liter or per kilo, which is the fair way to compare different package sizes. For the cheapest branch, give it an address or an intersection; for the personalized price, tell it how you pay (a bank card, a digital wallet, a points program) and which day you plan to go. And if you are planning the week's shopping, pass it the full list and ask which chain is best for each item.

Honest limits

Prices come from what each chain reports to SEPA, which is mandatory but doesn't always match the shelf price to the cent on a given day, especially with last-minute promotions. Coverage is that of the chains reporting to the system: corner stores, health food shops and wholesalers that are not in SEPA do not appear. Bank discounts are collected from what each bank or wallet publishes and come with conditions (refund caps, days, card type) worth verifying with the institution before counting on them. And when a discount source has gone several days without an update, the answer warns you instead of presenting it as current.

Frequently asked questions

Where do the supermarket prices come from?

From the SEPA program, the official system in which chains report the price of every product by branch every day (the same database behind Precios Claros), complemented with prices from the chains' online stores. It is loaded daily and every answer states which source and date the data is from.

Can I find the cheapest branch near my home?

Yes. Give it an address and the product, and the assistant tells you which nearby branch is cheapest, taking into account the promotions in force at each one.

Does it include bank and digital wallet discounts?

Yes. You can ask what discounts are available today with your card or wallet at each chain, which day is best to go, and ask for your real price by combining the product price with the supermarket's promotion and your payment method's discount.

Are the prices exact?

They are the ones the chains report to the official system, not a shelf survey. They may differ somewhat from what you see in the store, especially with daily deals. The answer always states the date of the data.
