Automated Supplier Price Scraper

I want to stop checking supplier portals one item at a time and instead trigger a script that pulls every SKU, full description and up-to-date price from the catalogues at https://www.mercante.com.br/, https://www.idbatacadistas.com.br/ and https://www.bartofil.com.br/...
