We put Estefa to work analyzing a classic pair of white sneakers in the Colombian market. Four sources, one suspicious pattern, and a find that pays for the month.
"Retail knows everything about you. Estefa exists so you know everything about retail."
Every recommendation shows its data. Every commission is the same at any store.
Every click is yours — we never fake it. That simple, that rare in this industry.
Estefa keeps you from getting ripped off. Yes, we said it.
Nothing, and the free plan will always be free. When you buy through an Estefa link, the store pays us a standard affiliate commission — the price for you is exactly the same as if you’d arrived on your own.
Through affiliate commissions. When you buy through an Estefa link, the store pays us a percentage of its marketing budget — it never comes out of your pocket and the price for you is the same. We earn the same wherever you buy, so we never recommend the pricier store to earn more: our business is that you shop well.
Always at the store. Estefa shows you the prices and takes you with one click to the product page at the store you choose; there you pay as usual (card, PSE, cash on delivery). Estefa never sees or touches your payment.
Three guarantees: the commission we receive is equivalent across stores (we don’t earn by sending you to the most expensive one); every analysis shows the price history and comparables so you can verify it; and we never activate an affiliate link without your click.
They compare U.S. stores. Estefa understands the real market here: Colombian retail, what it truly costs to import from Shein or Temu with duties and VAT, the local secondhand market, and the "discounts" of Black Days. And it also lives on WhatsApp — where shopping is really decided in Latin America.
We cross-reference public signals no one puts together: business registration and how long it’s operated, the age of its web domain, its reputation in reviews and marketplaces, whether it offers cash on delivery, and — the most valuable — delivery confirmations from other Estefa shoppers. With that we build a clear 1-to-10 index, with its reasons visible.
Honestly: from a distance no one can guarantee it 100% — and be wary of anyone who promises it. What Estefa does do is detect the warning signs with data: impossibly low prices versus the real range of the original, sellers outside authorized distributor lists, and visible inconsistencies in the photos. We tell you the risk level and what to check when it arrives.
