Cultural Tip
In Brazil most stores legally require the ‘nota fiscal’ for any exchange or return, because it serves as proof of purchase and tax documentation. However, many larger chains will still accept an exchange if you show a valid ID and the item is in its original condition. In smaller shops, the lack of a receipt often means the exchange is refused, so it’s polite to ask first with a phrase like this.
