"Good pricing on their website carrefour.com.br. Ok customer support"
Delivery time is a work of fiction. They show up 1 hour after the time (which is already a 2 hour window) without a single call.
Your list is also a work of fiction. Things are missing, not delivered, without a single acknowledgment from Carrefour, or my money back!
If you don't like roaches (specially going up your bread), avoid visiting the 24h Carrefour Express on Carrer Balmes, Barcelona. If you like them, or prefer your food "crunchy", you are in for a treat."
"Good value for money and excellent service."
