Cultural Tip
In Brazil, coupons (cupões) are very common in supermarkets, pharmacies and online stores, especially during promotional periods like "Black Friday". Using *posso* makes the request sound courteous. In Portugal, people often say *código promocional* instead of *cupom*, so you might hear *Posso usar este código promocional?*.
