It is common for cariocas Not to buy everything in the same place because prices and quality of the products are compared - for this reason, it is normal that one family purchases cleaning material in one shop, general edibles in another and vegetables in yet another, or a food market.

Another characteristic of carioca shops is to offer fidelity cards that provide discounts for customers that present them in the time of purchase. This is an attempt by some stores to make people buy more things in one single store.

For those who prefer aqcuiring their fruits and vegetables in a farmer's market, it is common that around 12h, when the markets are coming to the end, prices go lower in order to sell the products that remained after the initial purchase.

for those on a budget, it is worth reminding that things not commonly found in brazilian households may be highly priced, so sticking to local gastronomical traditions might be an economic idea.
