Many reputable shops and all department stores offer the latest in electronic equipment and cameras. There are camera shops that are especially popular among visitors located on Avenida Almeida Ribeiro near the Senado Square and on Avenida Horta e Costa near the "Three Lamps". Prices are comparatively low for the wide selection of high quality items in these shops. Larger shops are recommended for reliability after-sale service and it is advisable to ask for a warranty card along with your receipt. Beware of brand names you do not recognize on items in the smaller shops; they may be impossible to repair if problems occur later on.
