How to Track Prices on Mercado Livre, Amazon Brasil, Shopee & More in 2025

Brazil's ecommerce market is one of the fastest-growing in the world. Millions of consumers compare prices every day across platforms like Mercado Livre, Amazon Brasil, Shopee, Magalu, Americanas, Casas Bahia, Submarino, Ponto, and Extra — and prices can change dramatically from one day to the next.

For shoppers and online sellers, this creates a big challenge:

How do you know when the price you see is really the lowest price?

How do sellers stay competitive without constantly refreshing product pages?

That's where price tracking becomes essential.

In this guide, you'll learn how to track prices across the most popular ecommerce websites in Brazil, compare multiple stores at once, set price alerts, and make smarter buying or selling decisions — all using tools like PriceSense.

Why Prices Change So Quickly in Brazilian Ecommerce

Brazil's ecommerce ecosystem is dynamic and highly competitive. Several major factors affect price changes:

• Flash promotions
• Daily deals and limited-time discounts
• Seller competition inside marketplaces
• Seasonal sales (Black Friday, Carnaval, Christmas, Dia das Mães, Dia dos Namorados)
• Stock availability and logistics
• Regional pricing differences
• Currency fluctuations affecting imported goods

Example:

A smartphone on Mercado Livre may drop R$200 overnight because another seller launched a limited-time discount.

Shopee may drop prices heavily to boost seller ratings.

Amazon Brasil adjusts prices dynamically according to demand.

This makes manual tracking impossible — but automated tracking solves it.
