Cat is Irish, living in Buenos Aires. She recently compared what she pays through Peanut versus her card and the number was clear: 10% savings. Not on a special transaction or a lucky day, but on her regular, everyday spending. Groceries, restaurants, shops, and yes, even the dentist.

The Setup

Cat works in Buenos Aires and deposits regularly from her salary. She's not a short-term visitor: she lives here, shops here, goes to the doctor here. But without an Argentine DNI, she was financially stuck in tourist mode.

MercadoPago is how Buenos Aires works. Over 1,000,000 merchants accept it, from Carrefour to the corner kiosk. When Cat needed to pay, she pulled out her foreign Visa or Mastercard. When her neighbors and colleagues needed to pay, they scanned a QR code. Same store, same product, different price.

The Problem

Cards in Argentina convert at the MEP rate. The cripto dólar rate, what Peanut uses, gives you 5-8% more pesos per dollar. Add bank markups and foreign transaction fees on top of the MEP rate, and the total gap can easily hit 10% or more.

Cat saw this firsthand. A recent side-by-side comparison of her card charges versus what she pays through Peanut showed a clean 10% difference. On a full month of living expenses (rent, food, transport, healthcare), that's a significant amount of money back in her pocket.

And without a DNI, she had no alternative. She couldn't open MercadoPago, couldn't get a local bank account. Cards were her only option.

How She Uses Peanut

Cat deposits from her work salary into Peanut on a regular basis. Then she spends via MercadoPago QR everywhere she goes. And she means everywhere. The breadth of places she's used it tells the story better than any feature list:

  • Supermarkets and grocery stores
  • Restaurants and cafes
  • The dentist
  • Everyday shops and services

It works at any of the 1,000,000+ merchants that accept MercadoPago QR in Argentina. No DNI needed. No local bank account. She verified with her passport and started paying.

The Difference

The 10% is what stands out. It's specific, recent, and she measured it herself. But what changed her daily life is simpler than that: she can pay the same way everyone else does. No more being the person holding up the line with a foreign card. No more wondering if the card will be declined. She scans, it works, she moves on.

For an expat who lives here full-time, that's not a travel hack. That's how she manages her money.

In Her Words

"Compared to my card, I recently got 10% better rate. Huge savings on everyday spending."

"I don't have a DNI. Couldn't use MercadoPago before. Now I can pay like a local."

"I've used it everywhere, even at the dentist."
